| ====================================================================== |
| ============ Function 68, subfunction 30 - load PE-file ============== |
| ====================================================================== |
| Parameters: |
| * eax = 68 - function number |
| * ebx = 30 - subfunction number |
| * ecx = pointer to the string with path to file, |
| rules of path forming can be found in function 70 description. |
| Returned value: |
| * eax > 0xFFFFF000 - error, -eax = error code |
| * eax <= 0xFFFFF000 - pointer to the loaded file |
| Remarks: |
| * This function is to be called only by system loader from |
| kolibri.dll; the file loaded is not ready yet, it requires further |
| configuration. Use dlopen() from kolibri.dll instead of this |
| function. |
| ====================================================================== |
| =========== Function 68, subfunction 31 - unload PE-file ============= |
| ====================================================================== |
| Parameters: |
| * eax = 68 - function number |
| * ebx = 31 - subfunction number |
| * ecx = pointer to the loaded file |
| Returned value: |
| * eax = 0 - success |
| * eax = -1 - provided address does not correspond to any loaded file |
| Remarks: |
| * This function is to be called only by system loader from |
| kolibri.dll. Use dlclose() from kolibri.dll instead of this |
| function. |

| ===== Function 68, subfunction 32 - modify memory access rights ====== |
| ====================================================================== |
| Parameters: |
| * eax = 68 - function number |
| * ebx = 32 - subfunction number |
| * ecx = new access rights: zero or more of the following bits: |
| * PROT_READ = 1 - allow reading |
| * PROT_WRITE = 2 - allow writing |
| * PROT_EXEC = 4 - allow execution |
| * edx = pointer to begin of memory region |
| * esi = size of memory region in bytes |
| Returned value: |
| * eax = -1 - error |
| * else eax = old access rights |
| Remarks: |
| * The function modifies access rights to whole pages (4096 bytes). |
| * The function modifies access rights to all the pages intersecting |
| provided memory region. |
| * It is considered an error if a memory region returned by function |
| 68.22 is passed to this function. |
| * If any part of the passed memory region is incorrect, then the |
| function returns an error. However it is not guaranteed that |
| access rights of the correct part have been changed. |
| * If there was no error, the function returns old access rights of |
| the first provided page. |
| * Current implementation does not support execution access rights |
| without reading rights. Therefore bit PROT_EXEC is ignored on |
| entering the function, and becomes a copy of PROT_READ at exit. |
