PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

NAME
       pthread_getcpuclockid - access a thread CPU-time clock (ADVANCED REALTIME THREADS)

SYNOPSIS
       #include <pthread.h>
       #include <time.h>

       int pthread_getcpuclockid(pthread_t thread_id, clockid_t *clock_id);


DESCRIPTION
       The  pthread_getcpuclockid() function shall return in clock_id the clock ID of the CPU-time clock of the thread specified
       by thread_id, if the thread specified by thread_id exists.

RETURN VALUE
       Upon successful completion, pthread_getcpuclockid() shall return zero; otherwise, an error number shall  be  returned  to
       indicate the error.

ERRORS
       The pthread_getcpuclockid() function may fail if:

       ESRCH  The value specified by thread_id does not refer to an existing thread.


       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       The  pthread_getcpuclockid() function is part of the Thread CPU-Time Clocks option and need not be provided on all imple-
       mentations.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
