eax - SF_NETWORK_PROTOCOL (76)
|
||||
|
||||
======================================================================
|
||||
========== Function 77, Subfunction 0, Create futex object ===========
|
||||
======================================================================
|
||||
Parameters:
|
||||
* eax = 77 - function number
|
||||
* ebx = 0 - subfunction number
|
||||
* ecx = pointer to futex dword
|
||||
Returned value:
|
||||
* eax = futex handle, 0 on error
|
||||
Remarks:
|
||||
* Use subfunction 1 to destroy the futex.
|
||||
The kernel destroys the futexes automatically when the process
|
||||
terminates.
|
||||
======================================================================
|
||||
========= Function 77, Subfunction 1, Destroy futex object ===========
|
||||
======================================================================
|
||||
Parameters:
|
||||
* eax = 77 - function number
|
||||
* ebx = 1 - subfunction number
|
||||
* ecx = futex handle
|
||||
Returned value:
|
||||
* eax = 0 - successfull, -1 on error
|
||||
Remarks:
|
||||
* The futex handle must have been created by subfunction 0
|
||||
|
||||
======================================================================
|
||||
=============== Function 77, Subfunction 2, Futex wait ===============
|
||||
======================================================================
|
||||
Parameters:
|
||||
* eax = 77 - function number
|
||||
* ebx = 2 - subfunction number
|
||||
* ecx = futex handle
|
||||
* edx = control value
|
||||
* esi = timeout in system ticks or 0 for infinity
|
||||
Returned value:
|
||||
* eax = 0 - successfull, -1 on timeout
|
||||
|
||||
Remarks:
|
||||
* This functionn tests that the value at the futex dword still
|
||||
contains the expected control value, and if so, then sleeps
|
||||
waiting for a wake operation on the futex.
|
||||
* The futex handle must have been created by subfunction 0
|
||||
|
||||
======================================================================
|
||||
=============== Function 77, Subfunction 3, Futex wake ===============
|
||||
======================================================================
|
||||
Parameters:
|
||||
* eax = 77 - function number
|
||||
* ebx = 3 - subfunction number
|
||||
* ecx = futex handle
|
||||
* edx = number of waiters to wake
|
||||
Returned value:
|
||||
* eax = number of waiters that were woken up
|
||||
|
||||
Remarks:
|
||||
* This function wakes at most edx of the waiters that are
|
||||
waiting (e.g., inside futex wait) on the futex dword
|
||||
* The futex handle must have been created by subfunction 0
|
||||
|
||||
