tis_cond_signal(3)					     Library Functions Manual						tis_cond_signal(3)

NAME
tis_cond_signal - Wakes at least one thread that is waiting on the specified condition variable. LIBRARY
Standard C Library (libc.so, libc.a) SYNOPSIS
#include <tis.h> int tis_cond_signal( pthread_cond_t *cond); STANDARDS
None PARAMETERS
Address of the condition variable (passed by reference) on which to signal. DESCRIPTION
When threads are present, this routine unblocks at least one thread that is waiting on the specified condition variable cond. When threads are not present, this routine has no effect. For more information about actions taken when threads are present, refer to the pthread_cond_signal(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. ERRORS
None RELATED INFORMATION
Functions: tis_cond_broadcast(3), tis_cond_destroy(3), tis_cond_init(3), tis_cond_wait(3) Manuals: Guide to DECthreads and Programmer's Guide delim off tis_cond_signal(3)

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.
