pthread_unlock_global_np
pthread_unlock_global_np(3) Library Functions Manual pthread_unlock_global_np(3)
NAME
pthread_unlock_global_np - Unlocks the DECthreads global mutex.
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
SYNOPSIS
#include <pthread.h>
int pthread_unlock_global_np(void);
STANDARDS
None
PARAMETERS
None
DESCRIPTION
This routine unlocks the DECthreads global mutex. Because the global mutex is recursive, the unlock occurs when each call to
pthread_lock_global_np(3) has been matched by a call to this routine. For example, if you called pthread_lock_global_np(3) three times,
pthread_unlock_global_np(3) unlocks the global mutex when you call it the third time.
If no threads are waiting for the DECthreads global mutex, it becomes unlocked with no current owner. If one or more threads are waiting
to lock the global mutex, this routine causes one thread to unblock and try to acquire the global mutex. The scheduling policy is used to
determine which thread is awakened. For the policies SCHED_FIFO and SCHED_RR, a blocked thread is chosen in priority order, using first-
in/first-out (FIFO) within priorities.
RETURN VALUES
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows:
Successful completion. The mutex is unlocked or owned by another thread.
ERRORS
None
