SV_SIGNAL(D3) SV_SIGNAL(D3)
NAME
SV_SIGNAL - wake up one process sleeping on a synchronization
variable
SYNOPSIS
#include <sys/ksynch.h>
#include <sys/ddi.h>
void SV_SIGNAL(sv_t *svp, int flags);
Arguments
svp Pointer to the synchronization variable to be
signaled.
flags Bit field for flags. No flags are currently defined
for use in drivers and the flags argument must be
set to zero.
DESCRIPTION
If one or more processes are blocked on the synchronization
variable specified by svp, SV_SIGNAL wakes up a single blocked
process.
Return Values
None
USAGE
Note that synchronization variables are stateless, and
therefore calls to SV_SIGNAL only affect processes currently
blocked on the synchronization variable and have no effect on
processes that block on the synchronization variable at a
later time.
Level
Base or Interrupt.
Synchronization Constraints
Does not sleep.
Driver-defined basic locks, read/write locks, and sleep locks
may be held across calls to this function.
