tis_cond_wait(3)tis_cond_wait(3)NAMEtis_cond_wait - Causes a thread to wait for the specified condition
variable to be signaled or broadcast
SYNOPSIS
#include <tis.h>
int tis_cond_wait(
pthread_cond_t *cond,
pthread_mutex_t *mutex );
LIBRARY
Standard C Library (libc.so, libc.a)
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 con‐
dition 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
