PTHREAD_COND_SIGNAL(3)					   BSD Library Functions Manual 				    PTHREAD_COND_SIGNAL(3)

NAME
pthread_cond_signal -- unblock a thread waiting for a condition variable SYNOPSIS
#include <pthread.h> int pthread_cond_signal(pthread_cond_t *cond); DESCRIPTION
The pthread_cond_signal() function unblocks one thread waiting for the condition variable cond. RETURN VALUES
If successful, the pthread_cond_signal() function will return zero. Otherwise, an error number will be returned to indicate the error. ERRORS
pthread_cond_signal() will fail if: [EINVAL] The value specified by cond is invalid. SEE ALSO
pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3), pthread_cond_timedwait(3), pthread_cond_wait(3) STANDARDS
pthread_cond_signal() conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). BSD

PTHREAD_COND_WAIT(3)					   BSD Library Functions Manual 				      PTHREAD_COND_WAIT(3)

NAME
pthread_cond_wait -- wait on a condition variable SYNOPSIS
#include <pthread.h> int pthread_cond_wait(pthread_cond_t *cond, pthread_mutex_t *mutex); DESCRIPTION
The pthread_cond_wait() function atomically blocks the current thread waiting on the condition variable specified by cond, and releases the mutex specified by mutex. The waiting thread unblocks only after another thread calls pthread_cond_signal(3), or pthread_cond_broadcast(3) with the same condition variable, and the current thread reacquires the lock on mutex. RETURN VALUES
If successful, the pthread_cond_wait() function will return zero. Otherwise an error number will be returned to indicate the error. ERRORS
The pthread_cond_wait() function will fail if: [EINVAL] The value specified by cond or the value specified by mutex is invalid. SEE ALSO
pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3), pthread_cond_signal(3), pthread_cond_timedwait(3) STANDARDS
The pthread_cond_wait() function conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). Darwin February 16, 2006 Darwin
