tis_cond_broadcast(3)					     Library Functions Manual					     tis_cond_broadcast(3)

NAME

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

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <tis.h>

       int tis_cond_broadcast(
			pthread_cond_t	*cond);

STANDARDS

       None

PARAMETERS

       Address of the condition variable (passed by reference) on which to broadcast.

DESCRIPTION

       When threads are not present, this routine performs no actions.

       When threads are present, this routine unblocks all threads waiting on the specified condition variable cond.

       For more information about actions when threads are present, refer to the pthread_cond_broadcast(3) description.

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

tis_cond_wait(3)					     Library Functions Manual						  tis_cond_wait(3)

NAME

       tis_cond_wait - Causes a thread to wait for the specified condition variable to be signaled or broadcast.

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <tis.h>

       int tis_cond_wait(
			 pthread_cond_t      *cond,
			 pthread_mutex_t     *mutex);

STANDARDS

       None

PARAMETERS

       Address	of  the  condition variable (passed by reference) on which to wait.  Address of the mutex (passed by reference) that is associated
       with the condition variable specified in cond.

DESCRIPTION

       When threads are present, this routine causes a thread to wait for the specified condition variable cond to be signaled or broadcast.

       Calling this routine in a single-threaded environment is a coding error.  Because no other thread exists to issue a call  to  tis_cond_sig-
       nal(3) or tis_cond_broadcast(3), using this routine in a single-threaded environment forces the program to exit.

       For more information about actions taken when threads are present, refer to the pthread_cond_wait(3) description.

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 not a valid condition variable or the value specified by mutex is not a valid mutex,
       or:  Different  mutexes are supplied for concurrent tis_cond_wait(3) operations on the same condition variable, or: The mutex was not owned
       by the calling thread at the time of the call.

ERRORS

       None
