| SYSTEM FUNCTIONS of OS Kolibri 0.5.8.1 |
| |
| Number of the function is located in the register eax. |
| The call of the system function is carried out by the command "int 0x40". |
| All registers, except for obviously indicated in returned value, |
| including the register of flags eflags, are saved. |
| |
| |
| ====================================================================== |
| ============== Function 0 - define and draw the window. ============== |
| ====================================================================== |
| Defines an application window. Draws a frame of the window, header and |
| working area. For windows with ñêèíîì defines standard buttons of closing |
| and minimization. |
| Parameters: |
| * eax = 0 - number of the function |
| * ebx = [coordinate on axis x]*65536 + [size on axis x] |
| * ecx = [coordinate on axis y]*65536 + [size on axis y] |
| * edx = 0xXYRRGGBB, where: |
| * Y = style of the window: |
| * Y=0 - type I - window of the fixed sizes |
| * Y=1 - only to define window area, nothing to draw |
| * Y=2 - type II - window with changed sizes |
| * Y=3 - window with skinned |
| * other possible values (from 4 up to 15) reserved, |
| function call with such Y is ignored |
| * RR, GG, BB = accordingly red, green, blue |
| colours of a working area of the window |
| (is ignored for style Y=2) |
| * X = DCBA (bits) |
| * A = 1 - window has caption; if Y=3, caption string address could be passed in edi, |
| otherwise use function 71 subfunction 1 |
| * B = 1 - draw all graphics primitives relative to window client area |
| * C - reserved |
| * D = 8 - fill client area with gradient |
| other values are reserved |
| The following parameters are intended for windows of a type I and II, |
| and ignored for styles Y=1,3: |
| * esi = 0xXYRRGGBB - colour of header |
| * RR, GG, BB define colour |
| * Y=0 - usual window, Y=1 - unmovable window |
| * X defines a gradient of header: X=0 - no gradient, |
| X=8 - usual gradient, |
| for windows of a type II X=4 - negative gradient |
| * other values X and Y reserved |
| * edi = 0x00RRGGBB - colour of a frame |
| Returned value: |
| * function does not return value |
| Remarks: |
| * Location and the sizes of the window are installed by the first call of |
| this function and are ignored at subsequent; for change of location |
| and/or of sizes already of created window use function 67. |
| * If to use windows of appropriate styles, location and - or the sizes of |
| the window can vary by the user. |
| Current location and the sizes can be obtained by function 9. |
| * The window should be located on the screen. If the transferred coordinates |
| nd the sizes do not satisfy to this condition, appropriate coordinate |
| (or, probably, is considered both) as zero, and if also it does not help, |
| the appropriate size (or, probably, both) is installed in a size of the |
| screen. |
| |
| Further we shall designate xpos, ypos, xsize, ysize - values transmitted |
| in ebx, ecx. The coordinates are resulted concerning the left upper corner |
| of the window, which, thus, is set as (0,0), coordinate of the right lower |
| corner essence (xsize, ysize). |
| * The sizes of the window are understood in sense of coordinates of the |
| right lower corner. This concerns and to all other functions. It means, |
| that the real sizes on 1 pixel are more. |
| * Look of the window of a type I: |
| * draw external frame of colour indicated in edi, |
| in width 1 pixel |
| * draw header - rectangle with the left upper corner (1,1) and right lower |
| (xsize-1, min (25, ysize)) colour indicated in esi |
| (in view of a gradient) |
| * If ysize > =26, the working area of the window - rectangle with the left |
| upper corner (1,21) and right lower |
| (xsize-1, ysize-1) (sizes (xsize-1) * (ysize-21)) - colour |
| indicated in edx (in view of a gradient) is painted over |
| * Look of the window of a type Y=1: |
| * completely defined by the application |
| * Look of the window of a type II: |
| * draw external frame of width 1 pixel of the "shaded" colour |
| edi (all making colours decrease twice) |
| * drawn intermediate frame of width 3 pixels of colour edi |
| * draw internal frame of width 1 pixel |
| "shaded" colour edi |
| * draw header - rectangle with the left upper corner (4,4) |
| and right lower (xsize-4,min(20,ysize)) colour, indicated â esi |
| (in view of a gradient) |
| * If ysize > =26, the working area of the window is painted over - |
| rectangle with the left upper corner (5,20) and right lower |
| (xsize-5,ysize-5) - colour indicated in edx (in view of a gradient) |
| * Look of the window with skinned: |
| * draw external frame of width 1 pixel |
| colour 'outer' from skin |
| * draw intermediate framework of width 3 pixels |
| colour 'frame' from skin |
| * draw internal framework of width 1 pixel |
| colour 'inner' from skin |
| * draw header (on pictures from skin) in a rectangle |
| (0,0) - (xsize,_skinh-1) |
| * If ysize > =26, the working area of the window is painted over - |
| rectangle with the left upper corner (5, _skinh) and right lower |
| (xsize-5,ysize-5) - colour indicated in edx (in view of a gradient) |
| * two standard buttons are defined: closings and minimizations |
| (see function 8) |
| * value _skinh is accessible as result of call |
| subfunction 4 functions 48 |

| ====================================================================== |
| ================= Function 1 - put a point in the window. ============ |
| ====================================================================== |
| Parameters: |
| * eax = 1 - number of the function |
| * ebx = x-coordinate (concerning the window) |
| * ecx = y-coordinate (concerning the window) |
| * edx = 0x00RRGGBB - colour of a point |
| edx = 0x01xxxxxx - to invert colour of a point |
| (low 24 bits ignored) |
| Returned value: |
| * function does not return value |
| |
| ====================================================================== |
| ======== Function 2 - receive the code of the pressed key. =========== |
| ====================================================================== |
| Takes away the code of the pressed key from the buffer. |
| Parameters: |
| * eax = 2 - number of the function |
| Returned value: |
| * if the buffer is empty, comes back eax=1 |
| * If the buffer is nonblank, that comes back al=0, ah=code of the pressed key, |
| high word of the register eax is set zero |
| * If there is "hotkey", comes back |
| al=2, ah=scancode of the pressed key (0 for direction keys), |
| high word of the register eax contains a status of direction keys |
| at the moment of pressing a hotkey |
| Remarks: |
| * There is a common system buffer of the pressed keys by a size of 120 bytes, |
| organized as queue. |
| * There is one more common system buffer on 120 "hotkey". |
| * By call of this function the application with the inactive window |
| considers, that the buffer of the pressed keys is empty. |
| * By default this function returns ASCII-codes; to switch to the mode |
| scancode (and back) it is possible with usage of the function 66. |
| However, the hotkey always come back as scancodes. |
| * Ffind out, what keys correspond to what codes, is possible, having started |
| the applications keyascii and scancode. |
| * Scancodes come back directly by keyboard and are fixed; ASCII-codes turn |
| out with usage of the conversion tables, which can be installed |
| subfunction 2 functions 21 and to read subfunction 2 functions 26. |
| * As a consequence, ASCII-codes take into account current keyboard layout |
| (rus/en) as against scancodes. |
| * The information only about those hotkeys acts which were defined by this |
| stream subfunction 4 functions 66. |
| |
| ====================================================================== |

| for time 23:59:59 result will be 0x00595923 |
| Remarks: |
| * Look also subfunction 9 functions 26 - obtaining of time from the moment |
| of start of the system; it in many cases is more convenient, as returns |
| simply DWORD-value of the counter of time. |
| * System time can be installed by the function 22. |
| |
| ====================================================================== |
| ================ Function 4 - draw text in the window. =============== |
| ====================================================================== |

| * ebx = time in the 1/100 of second |
| Returned value: |
| * function does not return value |
| Remarks: |
| * The transmission ebx=0 does not transfer handle the following process |
| and at all does not make any operations. If really it is required to |
| transfer handle to the following process (to complete a current time |
| slice), use subfunction of 1 function 68. |
| * At current realization there will be an immediate return from the function, |
| if the addition ebx with current value of the counter of time will call |
| 32-bit overflow. |

| the same operations with the extended possibilities. |
| * Block = 512 bytes. |
| * For reading all file it is possible to specify the certainly large value |
| in edx, for example, edx = -1; but in this case be ready that the program |
| "will fall", if the file will appear too large and "will not be placed" in |
| memory of the program. |

| - purely name, last 3 - extension, the short names and extensions are |
| supplemented by blanks), or in the format 8.3 characters |
| "FILE.EXT" / "FILE.EX " (name no more than 8 characters, point, |
| extension 3 characters supplemented if necessary by blanks). |
| The filename should be written by capital letters. The completing |
| character with the code 0 is not necessary (ASCIIZ-string). |

| leaves on fulfilment of this thread) |
| * +4: word: position of the window of thread in the window stack |
| * +6: word: (there is no ratio to the requested thread) |
| number of the slot thread, which window is in the window stack |
| in a position ecx |

| or termination of the system |
| * 4 = thread is completed as a result of exception |
| * 5 = thread wait event |
| * 9 = requested slot is free, |
| all other information on the slot is not meaningful |
| Remarks: |
| * Slots are numbered with 1. |
| * Returned value not is a total number of streams, as there are free slots. |
| * Ïðè ñîçäàíèè ïðîöåññà àâòîìàòè÷åñêè ñîçäàåòñÿ thread âûïîëíåíèÿ. |
| * Function produces the information on thread. Each process has even one |
| thread. One process can create some thread, in this case everyone thread |
| receives the slot, and the fields +10, +22, +26 in these slots coincide. |
| For the applications there is no common way to define, whether two thread |
| belong to one process. |
| * Active window - window which is taking place on top of the window stack, |
| it receives the messages on a keyboard input. For it the position in the |
| window stack coincides with returned value. |
| * Slot 1 corresponds to special thread of an operating system, for which: |
| * window is in the bottom of the window stack, the fields +4 and +6 |
| contain value 1 |
| * Nname of the process - "OS/IDLE" (supplemented by blanks) |
| * address of the process is equal memory 0, size of used memory |
| 16 Mb (0x1000000) |
| * PID=1 |
| * coordinates and sizes of the window conditionally rely equal 0 |
| * status of the slot - always 0 (worked) |
| * The execution time adds of time leaving on purely operation, and down |
| time in waiting interruption (which can be received by call |
| subfunction 4 functions 18). |
| * Since the slot 2, the usual applications are placed. |
| * Usual applications are placed in memory to the address 0x10000000 |
| (constant of a kernel std_application_base_address). |
| Intersection does not occur, as for each process the own page table. |
| * At creation thread to it are assigned the slot in the system table and |
| identifier (Process/Thread IDentifier = PID/TID), which for given thread |
| do not vary in the subsequent time. |
| After completion thread its slot can be anew used for another thread. |
| The identifier thread can not be assigned to other stream even after |
| completion first. |
| Identifiers, assigned to new thread, monotonously grow. |
| * If thread yet has not defined the window by function call 0, |
| a location and the sizes of this window rely in zero. |
| * In the given moment the part of the buffer by a size 52 = 0x34 of byte |
| is used only. Nevertheless it is recommended to use the buffer |
| by a size 1 KB for the future compatibility, in the future some fields |
| can be added. |
| |

| ====================================================================== |
| Parameters: |
| * eax = 58 |
| * ebx = pointer on information structure |
| Returned value: |
| * eax = 0 - successfully; differently error code of a file system |
| * depending on subfunction the value and in other registers can come back |
| Common format of information structure: |
| * +0: dword: number subfunction |
| * +4: dword: number of block |
| * +8: dword: size |
| * +12 = +0xC: dword: pointer on data |

| /base/number/dir1/dir2/.../dirn/file, |
| where /base/number identifies the device, on which the file is searched: |
| one of |
| * /RD/1 = /RAMDISK/1 for access to ramdisk |
| * /FD/1 = /FLOPPYDISK/1 for access to first floppy - drive, |
| /FD/2 = /FLOPPYDISK/2 for second floppy - drive |

| (in this case base is defined subfunction 7 functions 21), |
| x - number of partition (beginning from 1) |
| * /HD0/x, /HD1/x, /HD2/x, /HD3/x for access accordingly |

| ======= Function 58, subfunction 0 - reading of a file/folder. ======= |
| ====================================================================== |
| Parameters: |
| * eax = 58 |
| * ebx = pointer on information structure |
| Format of information structure: |
| * +0: dword: 0 = number subfunction |
| * +4: dword: number of block for reading (beginning from 0) |
| * +8: dword: éuantity blocks for reading |
| * +12 = +0xC: dword: pointer on the buffer, where the data will be written |
| * +16 = +0x10: dword: pointer on the buffer for system operation |
| (4096 bytes) |
| * +20 = +0x14: ASCIIZ-name of the file, the rules of creation of names |
| are indicated in the common description |
| Returned value: |
| * eax = 0 - successfully, differently error code of a file system |
| * ebx = file size (in bytes) or |
| -1=0xffffffff, if the file is not retrieved |
| Remarks: |
| * Size of block - 512 bytes. |
| * This function is obsolete, for reading files use subfunction 0 |
| functions 70, for reading folders - subfunction of 1 function 70. |
| * Function allows to read contents of a folder. From file systems is |
| supported only FAT. The format of a FAT-folder is described in any |
| documentation on FAT. |
| * Size of a folder is defined on a size of a chain of clusters in FAT. |
| * If the file was terminated earlier, than last requested block was read, |
| the function will read, how many can, then will return eax=6 (EOF). |
| * Function allows to read root folders /rd/1, /fd/x, /hd [n] /x, but |
| in first two cases the current implementation does not follow the |
| installed rules: |
| for /rd/1: |
| * if 0 blocks for reading are indicated, it is considered, |
| that is requested 1; |
| * if is requested more than 14 blocks or the initial block is not |
| less 14, comes back eax=5 (not found) and ebx =-1; |
| * size of the root ramdisk = 14 blocks, 0x1C00=7168 bytes; but comes |
| back ebx=0 (except for a case of the previous item); |
| * strangely enough, it is possible to read 14 block (there, generally |
| speaking, garbage - I remind, the score carries on with 0); |
| * if one block with number, not smaller 14 was requested even, |
| comes back eax=6 (EOF); differently eax=0. |
| for /fd/x: |
| * if the initial block is not less 14, comes back eax=5 (not found) |
| and ebx=0; |
| * by the way speaking, the format FAT12 admits diskettes with a size |
| of the root less or more than 14 blocks; |
| * checks of length is not done; |
| * if it was possible to read given with a diskette, comes back eax=0, |
| ebx=0; otherwise eax=10 (access denied), ebx =-1. |
| * Function handles reading special folders /, /rd, /fd, /hd [n]; but the |
| result does not correspond expected (on operation with usual |
| files/folders), does not follow the installed rules, can vary in the |
| following versions of a kernel and consequently is not described. |
| For obtaining the information about the equipment use subfunction 11 |
| functions 18 or read appropriate folders subfunction of 1 function 70. |
| |
| ====================================================================== |
| ======== Function 58, subfunction 1 - overwriting of the file. ======= |

| * +8: dword: number bytes for writing |
| * +12 = +0xC: dword: pointer on data for çàïèñè |
| * +16 = +0x10: dword: pointer on buffer for system operation |
| (4096 bytes) |
| * +20 = +0x14: ASCIIZ-name of file, the rules of creation of names |
| are indicated in the common description |
| Returned value: |
| * eax = 0 - successfully, differently error code of a file system |
| * ebx fail |
| Remarks: |
| * This function is obsolete, use subfunction 2 functions 70. |
| |
| ====================================================================== |
| ====== Function 58, subfunction 2 - deleting of a file/folder. ======= |
| ====================================================================== |
| Parameters: |
| * eax = 58 - number of the function |
| * ebx = pointer on information structure |
| Format of information structure: |
| * +0: dword: 2 = number subfunction |
| * +4: dword: ignored |
| * +8: dword: ignored |
| * +12 = +0xC: dword: ignored |
| * +16 = +0x10: dword: pointer on buffer for system operation |
| (4096 bytes) |
| * +20 = +0x14: ASCIIZ-name of file, the rules of creation of names |
| are indicated in the common description |
| Returned value: |
| * eax = 0 - successfully, differently error code of a file system |
| * ebx fail |
| Remarks: |
| * By operation with a diskette it is not necessary to delete a nonblank |
| folder. The code of operation with the hard disk nonblank folders |
| deletes correctly (i.e. recursively with all files and nested folders). |
| Ramdisk of folders does not support. |
| |
| ====================================================================== |
| === Function 58, subfunction 3 - writing data in the existing file === |
| ====================================================================== |
| Parameters: |
| * eax = 58 - number of the function |
| * ebx = pointer on information structure |
| Format of information structure: |
| * +0: dword: 3 = number subfunction |
| * +4: dword: initial position in the file; -1 = to add in the end |
| * +8: dword: number bytes for writing |

| (4096 bytes) |
| * +20 = +0x14: ASCIIZ-name of file, the rules of creation of names |
| are indicated in the common description |
| Returned value: |
| * eax = 0 - successfully, differently error code of a file system |
| * ebx fail |
| Remarks: |
| * Ramdisk and the diskettes do not support this function, |
| it only for hard disks. |
| * File should already exist (differently comes back 5, not found). |
| For creation of files use subfunction 1. |
| * If the initial position is more than a file size, comes back eax=6 (EOF). |
| If the finite position is more than a file size, the file extends. |
| * Code of processing of data writing for the hard disk interpretes zero |
| value of a field +8 as the instruction of a truncation of the file |
| up to a size indicated in a field +4. However code of processing of |
| 58-th function locks this possibility for the applications, at once |
| returning handle (with eax=0) in case of a zero size. |

| ====== Function 58, subfunction 8 - LBA-reading from the device. ===== |
| ====================================================================== |
| Parameters: |

| (512 bytes) |
| * +16 = +0x10: dword: pointer on buffer for system operation |
| (4096 bytes) |
| * +20 = +0x14: ASCIIZ-name of the device: is not sensitive to the register, |
| one of /rd/1 = /RamDisk/1, /hd/n = /HardDisk/n, |
| 1<=n<=4 - number of device: 1=IDE0, ..., 4=IDE3. |
| Instead of digits is admitted, though usage 'first', 'second', 'third', |
| 'fourth' is not recommended for convenience of transition on the future |
| extensions. |
| Returned value: |
| * if device name /hd/xxx is indicated, where xxx is not in list above: |
| * eax = ebx = 1 |
| * if the incorrect device name is indicated |
| (except for the previous case): |
| * eax = 5 |
| * ebx does not vary |
| * if the LBA-access is prohibited subfunction 11 functions 21: |
| * eax = 2 |
| * ebx fail |
| * for ramdisk attempt of reading of the block outside ramdisk |
| (18*2*80 blocks) results to |
| * eax = 3 |
| * ebx = 0 |
| * at successful reading: |
| * eax = ebx = 0 |
| Remarks: |
| * Size of the block - 512 bytes; one block is read. |
| * It is not necessary to rely on returned value, it can vary in |
| the following versions. |
| * It is required, that the LBA-access to devices subfunction 11 functions 21 |
| should be allowed. Find out it it is possible by call |
| subfunction 11 functions 26. |
| * LBA-reading of a diskette is not supported. |
| * Function reads out the data of the physical hard disk; if for any reasons |
| the data of the concrete unit are necessary, will come to define initial |
| sector of this unit (or directly through MBR, or from the extended |
| structure returned same subfunction 11 functions 18). |
| * Function the error code of the hard disk does not check, so search of |
| nonexistent sector all the same something will read (more probably |
| everything, zero, but it is defined by the device) and it will be |
| considered as success (eax=0). |
| |
| ============================================================================= |
| = Function 58, subfunction 15 - obtaining of information about a file system. |
| ============================================================================= |
| Parameters: |
| * eax = 58 - number of the function |
| * ebx = pointer on information structure |
| Format of information structure: |
| * +0: dword: 15 = number of the function |
| * +4: dword: ignored |
| * +8: dword: ignored |
| * +12 = +0xC: dword: ignored |
| * +16 = +0x10: dword: ignored |
| * +20 = +0x14: (second character is checked only, at once after /) |
| /rd=/RAMDISK or /hd=/HARDDISK |
| Returned value: |
| * If second character does not belong to set {'r','R','h','H'}: |
| * eax = 3 |
| * ebx = ecx = dword [fileinfo] = 0 |
| * for ramdisk: |
| * eax = 0 (success) |
| * ebx = total number of clusters = 2847 |
| * ecx = number of free clusters |
| * dword [fileinfo] = cluster size = 512 |
| * for the hard disk: base and partition are defined |
| subfunctions 7 and 8 functions 21: |
| * eax = 0 (success) |
| * ebx = total number of clusters |
| * ecx = number of free clusters |
| * dword [fileinfo] = cluster size (in bytes) |
| Remarks: |
| * Be not surprised to strange layout of 4-th returned parameter - when this |
| code was written, at system calls to the application the registers eax, |
| ebx, ecx (from pushad-structure transmitted as argument to the system |
| function) came back only. Now it is corrected, so, probably, it is |
| meaningful to return a cluster size in edx, while this function have |
| not begun to use |
| * Generally still exists subfunction 11 functions 18, returning the |
| information on a file system. Under the extended table of a disk |
| subsystem it is possible to define a cluster size (there it is stored |
| in sectors) and total number of clusters for hard disks. |

| of a file system |
| Remarks: |
| * This function is obsolete, use subfunction 7 functions 70. |
| * Command line should be ended by the character with the code 0 |
| (ASCIIZ-strings); it are taken into account or all characters up to |
| completing zero inclusively, or the first 256 characters, that are less. |
| * If the process is started as debugged, it creates in the frozen status; |
| for start use subfunction 5 functions 69. |

| ====================================================================== |
| ======== Function 59 - get information on last system calls. ========= |
| ====================================================================== |
| Get data on all system calls of all processes. |
| Parameters: |

| * ebx = 0 - sole subfunction |
| * ecx = pointer on buffer |
| * edx = size of buffer |
| Returned value: |
| * eax = total number of system calls made from moment |

| * +56 = +0x38: dword: ecx |
| * +60 = +0x3C: dword: eax (=number system function) |
| Remarks: |
| * Function is used only in the application systrace. It is rather difficult |
| to present a situation, in which this application or this function are |
| really useful, and all system calls for support of this function are a |
| little decelerated (though and not strongly)... |
| * In this connection there is a sentence support of this function from |
| a kernel to remove absolutely, together with the application systrace. |
| * Information on system calls is saved in system ring buffer |
| on 0x10 of inputs. |
| This function simply copies the indicated size given from the mentioned |
| buffer to the indicated address. |
| * To what from inputs in the buffer corresponds to last call, it is possible |
| to define on value eax, namely, |
| input (eax and 0xF) (on offset (eax and 0xF) *0x40). |
| * In current implementation the seldom meeting problems of |
| unsynchronization are possible, when about some calls the |
| information becomes outdated. |
| * Under the system buffer the page, 4 KB is allocated. |
| Size of an input = 64 bytes. |
| Why 16 inputs - not clearly are used only. |
| * Value esp at moment of system call by this function cannot be found out. |
| * Checks of a correctness edx in current implementation is not done. |

| Ôîðìàò IPC-áóôåðà: |
| * +0: dword: if here not 0, the buffer is considered disabled; lock/unblock |
| the buffer, when you with it actively work also to you it is necessary, |
| that the data of the buffer from the outside varied |
| (the new messages) not acted |
| * +4: dword: occupied place in the buffer (in bytes) |
| * +8: first message |
| * +8+n: second message |
| * ... |
| Format of message: |
| * +0: dword: PID of process / thread which has transmitted the message |
| * +4: dword: length of the message (not including this header) |

| * eax = 60 - number of the function |
| * ebx = 2 - number subfunction |
| * ecx = PID of receiver |
| * edx = pointer on message data |
| * esi = length of message (in bytes) |
| Returned value: |
| * eax = 0 - successfully |
| * eax = 1 - receiver has not defined buffer for IPC-messages |
| (can be, was not in time yet, and there can be, it not that thread, |
| which is necessary) |
| * eax = 2 - receiver has blocked the IPC-buffer; try slightly to wait |
| * eax = 3 - overflow of IPC-buffer of receiver |
| * eax = 4 - process/thread with such PID does not exist |
| Remarks: |
| * System at once after writing the IPC-message in the buffer dispatches |
| to stream - receiver event with the code 7 (see codes of events). |
| |
| ====================================================================== |
| ==== Function 61 - get parameters for direct access to a graphics. === |
| ====================================================================== |
| Data of graphics screen are accessible to program (area of memory, which purely |
| also displays contents of screen) directly without calls of system functions |
| through the selector gs: |
| mov eax, [gs:0] |
| will place in eax first dword of buffer containing information on colour |
| of left upper point (and, probably, colour of several following). |
| mov [gs:0], eax |
| by operation in modes VESA c LFB will install colour of left upper point |
| (and, probably, colour of several following). |
| Interpretations given of the graphics screen need knowledge of some parameters, |
| which come back by this function. |
| Remarks: |
| * Parameters of a graphics very seldom vary at system operation, namely, |
| only in cases, when the user works with the program VRR. |
| * At change of videomode the system redraw all windows |
| (event with the code 1) and redraw a background (event 5). |
| Same events occur and in other cases, which meet much more often, |
| than change of videomode. |
| * By operation in videomodes with LFB the selector gs specifies on purely |
| LFB, so reading / writing on gs result directly in change of contents of |
| the screen. By operation in videomodes without LFB gs specifies some area |
| of the given kernel, and all functions of output on the screen honesty |
| fulfil double operation on writing directly on the screen and on |
| writing in this buffer. In result at reading contents of this buffer the |
| results correspond to contents of the screen (with, generally speaking, |
| large colour permission), and writing ignored. |
| Exception is the mode 320*200, for which in main loop system thread the |
| upgrade of the screen is fulfilled according to movements |
| of a mouse pointer. |

| ====================================================================== |
| ============== Function 63 - work with debugging board. ============== |
| ====================================================================== |
| Debugging board represents the system buffer (on 512 bytes), in which any |
| program can write (generally speaking, arbitrary) data and from which other |
| program can these data read. |
| There is an agreement, according to which written given - text strings |
| interpreted as of the debug message on a course of execution of the program. |
| The kernel in the defined situations also writes to board of debugging of the |
| item of information about execution of some functions; under the agreement of |
| the message of a kernel start with the prefix " K: ". |
| For review of board of debugging the application board is created which reads |
| out the data from the buffer and displays them in the window. board understands |
| a sequence of codes 13,10 as transition on new string |
| Character with the zero code at the end of string is not mandatory, |
| but also does not prevent. |
| As has appeared of the debugger necessity of board of debugging a little has |
| decreased, as the debugger allows completely to inspect a course of execution |
| of the program, and for this purpose it is not required of any efforts on the |
| part of the program. Nevertheless in many cases the board of debugging |
| continues to remain useful. |

| At overflow of the buffer all obtained data are lost also filling |
| starts again with zero. |
| * For output to board of debugging of more complex objects (strings, numbers) |
| this function called in cycle suffices. It is possible to not write |
| manually appropriate code, and to take advantage of the file debug.inc, |
| included in the distribution kit. |
| |

| * If in DBID there is a name in ASCII, length makes 304 bytes, |
| if in UNICODE - 560 bytes. Value of length aligned on whole |
| multiple 16 bytes (for of acceleration of processing in cache-memory CPU). |
| * First character after a name zero (ASCIIZ-string). |
| The further data contain garbage. |
| * If the files in a folder were terminated earlier, than the requested |
| amount was read, the function will read, how many can, |
| then will return eax=6 (EOF). |
| * Any folder on the disk, except for root, contains two special |
| inputs(entrances) "." And "..", identifying accordingly folder |
| and parent folder. |
| * Function allows also to read virtual folders "/", "/rd", "/fd", |
| "/hd [n] ", thus the attributes subfolders rely equal 0x10, and the times |
| and dates are unset. An alternate way of obtaining of the information |
| about the equipment - subfunction 11 functions 18 |

| -eax contains an error code of a file system |
| * ebx fail |
| Remarks: |
| * Command line should be ended by the character with the code 0 |
| (ASCIIZ-strings); it are taken into account or all characters up to |
| completing zero inclusively, or the first 256 characters, that are less. |

| |
| ====================================================================== |
| =========== Function 71, subfunction 1 - set window caption ========== |
| ====================================================================== |
| Parameters: |
| * eax = 71 - function number |
| * ebx = 1 - subfunction number |
| * eáx = caption string address |
| Returned value: |
| * eax = 0 - caption changed successfully |
| * eax = 1 - error occured |
| Remarks: |
| * String should be in ASCIIZ format. Disregarding real string length, |
| no more than 255 chars will be wrawn. |

| ====================================================================== |
| ========== Function -1 - complete execution of thread/proces ========= |
| ====================================================================== |
| Parameters: |
| * eax = -1 - number of the function |
| Returned value: |
| * function does not return neither value, nor handle |
| Remarks: |
| * If the process obviously did not create streams, it has only one thread, |
| which completion results in completion of the process. |
| * If current thread - last in process, its completion also results |
| in completion of the process. |
| * This function completes current thread. Another thread |
| is possible kill by call subfunction 2 functions 18. |
| |
| ====================================================================== |
| =========================== List of events =========================== |
| ====================================================================== |
| Next event is possible get by call of one from functions 10 (to expect event), |
| 11 (to check up without waiting), 23 (to expect during the given time). |
| These functions return only those events, which enter into a mask installed by |
| the function 40. By default it is first three, that there is enough for of many |
| applications of. |
| Codes of events: |
| * 1 = message about redraw (is reset at function call 0) |
| * 2 = key on keyboard is pressed (acts, only when the window is active) |
| or "hotkey" is pressed; is reset, when all keys from the buffer are read |
| out by the function 2 |
| * 3 = button is pressed, defined earlier by function 8(or buttons of closing, |
| created implicitly by function 0 is pressed; the button of minimization is |
| handled by the system and about it of the message does not come; acts, only |
| when the window is active; is reset, when all buttons from the buffer are |
| read out by the function 17) |
| * 4 = reserved (in current implementation never comes even at unmasking |
| by the function 40) |
| * 5 = redraw the background of a desktop (is reset automatically after |
| redraw, so if in time redraw of a background the program does not wait |
| and does not check event, this event it will not remark) |
| * 6 = event from the mouse (something happened - pressing a mouse button |
| or moving; is reset at reading) |
| * 7 = there was an event IPC (look the function 60 - Inter Process |
| Communication; is reset at reading) |
| * 8 = there was a network event (is reset at reading; look operation |
| with the network) |
| * 9 = there was a debug event (is reset at reading; look a debug subsystem) |
| * 16..31 = there was an event with appropriate IRQ |
| (16=IRQ0, 31=IRQ15) (is reset at reading all data IRQ) |
| |
| ====================================================================== |
| ==================== Error codes of a file system ==================== |
| ====================================================================== |
| * 0 = successfully |
| * 1 = base and/or partition of the hard disk is not defined |
| (subfunctions 7, 8 functions 21) |
| * 2 = function is not supported for of the given file system |
| (comes back in case of attempt of LBA-reading at prohibited LBA) |
| * 3 = Unknown file system |
| * 4 = comes back only by function rename by transmission of the strongly |
| incorrect parameter and in any way does not correspond to the description |
| in sources of a kernel " partition not defined at hd " |
| * 5 = file is not retrieved |
| * 6 = file was completed |
| * 7 = pointer outside of memory of the application |
| * 8 = disk is filled |
| * 9 = table FAT is destroyed |
| * 10 = access denied |
| * 11 = error of the device |
| At start of the program the following error codes are possible also: |
| * 30 = 0x1E = not enough of memory |
| * 31 = 0x1F = file is not application |
| * 32 = 0x20 = too much processes |
