SV_SIGNAL(D3)

SV_SIGNAL - wake up a process sleeping on a synchronization variable

Showing IRIX 6.5.30 (default release). Unchanged since IRIX 6.5.

NAME
     SV_SIGNAL - wake up a process sleeping on a synchronization variable

SYNOPSIS
     #include <sys/ksynch.h>
     #include <sys/ddi.h>
     int SV_SIGNAL(sv_t *svp);

   Arguments
     svp       Pointer to the synchronization variable to be signaled.

DESCRIPTION
     If one or more processes are blocked on the synchronization variable
     specified by svp, SV_SIGNAL wakes up a single blocked process.  Note that
     synchronization variables are stateless -- calls to SV_SIGNAL only affect
     processes currently blocked on the synchronization variable.

   Return Values
     Returns 1 if a process was unblocked, 0 otherwise.

   Level
     Base or Interrupt.

   Synchronization Constraints
     Does not sleep.

     Driver-defined basic locks and read/write locks may be held across calls
     to this function.
