tis_cond_wait(3)
NAME
  tis_cond_wait - Causes a thread to wait for the specified condition
  variable to be signaled or broadcasted.

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

  mutex	    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 thread can execute in parallel to issue a call to
  tis_cond_signal(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:

  0	    Successful completion.

  [EINVAL]  The value specified by cond, or mutex is invalid, 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
