PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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 implementations.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
