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

NAME
pthread_cond_destroy -- destroy a condition variable LIBRARY
POSIX Threads Library (libpthread, -lpthread) 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. IMPLEMENTATION NOTES
A condition variable can be destroyed immediately after all the threads that are blocked on it are awakened. RETURN VALUES
If successful, the pthread_cond_destroy() function will return zero, otherwise an error number will be returned to indicate the error. ERRORS
The pthread_cond_destroy() function will fail if: [EINVAL] The value specified by cond is invalid. [EBUSY] The variable cond is locked by another thread. SEE ALSO
pthread_cond_broadcast(3), pthread_cond_init(3), pthread_cond_signal(3), pthread_cond_timedwait(3), pthread_cond_wait(3) STANDARDS
The pthread_cond_destroy() function 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 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''). BSD
