| 3619 | * eax = 68 - function number |
3620 | * eax = 68 - function number |
| 3620 | * ebx = 14 - subfunction number |
3621 | * ebx = 14 - subfunction number |
| 3621 | * ecx = pointer to the buffer for information (8 bytes) |
3622 | * ecx = pointer to the buffer for information (24 bytes) |
| 3622 | Returned value: |
3623 | Returned value: |

| 3626 | Remarks: |
3625 | * +0: dword: identifier for underlying data of signal |
| 3627 | * The current implementation at wait time uses "heavy" operations |
3626 | * +4: data of signal (20 bytes), format of which is defining by |

| 3633 | Parameters: |
3632 | Parameters: |
| 3634 | * eax = 68 - function number |
3633 | * eax = 68 - function number |
| - | 3634 | * ebx = 15 - subfunction number |
|
| 3635 | * ebx = 15 - subfunction number |
3635 | * ecx = address of the new exception handler |
| 3636 | * ecx = address of the new exception handler |
3636 | * edx = the mask of processing exceptions |
| - | 3637 | Returned value: |
|
| - | 3638 | * eax = address of the old exception handler (0, if it was not set) |
|
| - | 3639 | * ebx = the old mask of exception handler |
|
| - | 3640 | Remarks: |
|
| - | 3641 | * Bit number in mask of exceptions is correspond to exception number |
|
| - | 3642 | by CPU-specification (Intel-PC). For example, FPU-exception have |
|
| - | 3643 | number 16 (#MF), and SSE-exception - 19 (#XF) |
|
| - | 3644 | * The current implementation ignore the inquiry for hook of 7 |
|
| - | 3645 | exception - system process #NM by one's own. |
|
| - | 3646 | * User handler get exception number in stack parameter. So, correct |
|
| - | 3647 | exit from handler is: RET 4. Return from handler is to the same |
|
| - | 3648 | instruction, that was cause the exception |
|
| - | 3649 | * When control is transfering to user handler, corresponding bit in |
|
| - | 3650 | exception mask is clearing. Rising this exception in consequence |
|
| - | 3651 | - reduce to default-handling. Exactly: terminating the application, |
|
| - | 3652 | or suspending with debug-notify to owner. |
|
| - | 3653 | * After completion of critical operations in user handler, it may be |
|
| - | 3654 | rising corresponding bit in exception mask by using subfunction 18 |

| 3637 | Returned value: |
3655 | Clearing exceptions flags in FPU and/or XMM modules - is |
| 3638 | * eax = address of the old exception handler (0, if it was not set) |
3656 | responsibility of user handler too. |

3699 | Parameters: |
| 3682 | * eax = 68 - function number |
3700 | * eax = 68 - function number |
| - | 3701 | * ebx = 15 - subfunction number |
|
| 3683 | * ebx = 15 - subfunction number |
3702 | * ecx = signal number |
| 3684 | * ecx = address of the new exception handler |
3703 | * edx = value of activity (0/1) |
| 3685 | Returned value: |
3704 | Returned value: |
| - | 3705 | * eax = value of old activity for this signal (0/1) |
|
| - | 3706 | Remarks: |
|
| - | 3707 | * In current implementation, it is changed only exception mask for |
|
| - | 3708 | user exception handler, wich was previously set by subfunction 15. |

| 3686 | * eax = address of the old exception handler (0, if it was not set) |
3709 | At that, number of signal correspond to exception number. |
