pthread_cond_broadcast(3)				     Library Functions Manual					 pthread_cond_broadcast(3)

NAME

       pthread_cond_broadcast - Wakes all threads that are waiting on the specified condition variable.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int pthread_cond_broadcast(
			pthread_cond_t	*cond);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS

       Condition variable upon which the threads (to be awakened) are waiting.

DESCRIPTION

       This  routine unblocks all threads waiting on the specified condition variable cond.  Calling this routine implies that data guarded by the
       associated mutex has changed, so that it might be possible for one or more waiting threads to proceed.	The  threads  that  are  unblocked
       shall contend for the mutex according to their respective scheduling policies (if applicable).

       If  only  one  of  the  threads	waiting  on  a	condition  variable  may  be  able to proceed, but any single thread can proceed, then use
       pthread_cond_signal(3) instead.

       Whether the associated mutex is locked or unlocked, you can still call this  routine.   However,  if  predictable  scheduling  behavior	is
       required, that mutex should then be locked by the thread calling the pthread_cond_broadcast(3) routine.

       If  no threads are waiting on the specified condition variable, this routine takes no action.  The broadcast does not propagate to the next
       condition variable wait.

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 value specified by cond is invalid.

ERRORS

       None
