PTHREAD_GETCPUCLOCKID(3P)				     POSIX Programmer's Manual					 PTHREAD_GETCPUCLOCKID(3P)

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

       No errors are defined.

       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

       If  an  implementation detects use of a thread ID after the end of its lifetime, it is recommended that the function should fail and report
       an [ESRCH] error.

FUTURE DIRECTIONS

       None.
