NAME

       pthread_delay_np - Delays a thread's execution.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int  pthread_delay_np(
			const struct timespec	 *interval);

STANDARDS

       None

PARAMETERS

       Number of seconds and nanoseconds to delay execution.  The value specified for each must be greater than or equal to zero.

DESCRIPTION

       This  routine causes a thread to delay execution for a specific interval of time. This interval ends at the current time plus the specified
       interval.  The routine will not return before the end of the interval is reached, but may return an arbitrary amount of time after the  end
       of the interval is reached. This can be due to system load, thread priorities, and system timer granularity.

       Specifying an interval of zero (0) seconds and zero (0) nanoseconds is allowed and can be used to force the thread to give up the processor
       or to deliver a pending cancelation request.

       The timespec structure contains the following two fields: tv_sec is an integral number of  seconds.   tv_nsec  is  an  integral	number	of
       nanoseconds.

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 interval is invalid.

ERRORS

       None

pthread_cond_signal_int_np(3)				     Library Functions Manual				     pthread_cond_signal_int_np(3)

NAME

       pthread_cond_signal_int_np - Wakes one thread that is waiting on the specified condition variable (called from interrupt level only).

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int pthread_cond_signal_int_np(
			   pthread_cond_t    *cond);

STANDARDS

       None

PARAMETERS

       Condition variable to be signaled.

DESCRIPTION

       This routine wakes one thread waiting on the specified condition variable.  It can only be called from a software interrupt handler routine
       (that is, from a Tru64 UNIX signal handler or OpenVMS AST).  Calling this routine implies that it might be possible for	a  single  waiting
       thread to proceed.

       The  scheduling policies of the waiting threads determine which thread is awakened.  For policies SCHED_FIFO and SCHED_RR, a blocked thread
       is chosen in priority order, using first-in/first-out (FIFO) within priorities.

       This routine does not cause a thread blocked on a condition variable to resume execution immediately. A thread resumes  execution  at  some
       time after the interrupt handler routine returns.

       You  can  call this routine regardless of whether the associated mutex is locked (by some other thread).  Never lock a mutex from an inter-
       rupt handler routine.

									  Note
       This routine allows you to signal a thread from a software interrupt handler.  Do not call this routine from noninterrupt code.	To  signal
       a thread from the normal noninterrupt level, use pthread_cond_signal(3).

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
