---------------------- Constants for registers: ----------------------
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
