NAME    [Toc]    [Back]

       pthread_delay_np - Delays a thread's execution

SYNOPSIS    [Toc]    [Back]

       #include <pthread.h>

       int pthread_delay_np(
               const struct timespec *interval );

LIBRARY    [Toc]    [Back]

       DECthreads POSIX 1003.1c Library (libpthread.so)

STANDARDS    [Toc]    [Back]

       None

PARAMETERS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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 cancellation
 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    [Toc]    [Back]

       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.
