PTHREAD_COND_DESTROY(3) 				   BSD Library Functions Manual 				   PTHREAD_COND_DESTROY(3)

NAME

     pthread_cond_destroy -- destroy a condition variable

SYNOPSIS

     #include <pthread.h>

     int
     pthread_cond_destroy(pthread_cond_t *cond);

DESCRIPTION

     The pthread_cond_destroy() function frees the resources allocated by the condition variable cond.

RETURN VALUES

     If successful, the pthread_cond_destroy() function will return zero.  Otherwise, an error number will be returned to indicate the error.

ERRORS

     pthread_cond_destroy() will fail if:

     [EBUSY]		The variable cond is locked by another thread.

     [EINVAL]		The value specified by cond is invalid.

SEE ALSO

     pthread_cond_broadcast(3), pthread_cond_init(3), pthread_cond_signal(3), pthread_cond_timedwait(3), pthread_cond_wait(3)

STANDARDS

     pthread_cond_destroy() conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').

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

NAME

     pthread_cond_wait -- wait on a condition variable

LIBRARY

     POSIX Threads Library (libpthread, -lpthread)

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.

     [EPERM]		The specified mutex was not locked by the calling thread.

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'').
