SYNOPSIS
#include <pthread.h> int pthread_cond_broadcast( pthread_cond_t *cond);
PARAMETERS
condCondition variable broadcast.
DESCRIPTION
The pthread_cond_broadcast() routine wakes all threads waiting on a condition variable. 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. If any one waiting thread might be able to proceed, call pthread_cond_signal(). Call this routine when the associated mutex is either locked or unlocked.
RETURN VALUES
If the function fails, errno may be set to one of the following values:
| Return | Error | Description |
| 0 | Successful completion. | |
| \-1 | [EINVAL] | The value specified by cond is invalid. |
