PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

13       pthread_getcpuclockid — access a thread CPU-time clock (ADVANCED  REAL‐
14       TIME THREADS)
15

SYNOPSIS

17       #include <pthread.h>
18       #include <time.h>
19
20       int pthread_getcpuclockid(pthread_t thread_id, clockid_t *clock_id);
21

DESCRIPTION

23       The pthread_getcpuclockid() function shall return in clock_id the clock
24       ID of the CPU-time clock of the thread specified by thread_id,  if  the
25       thread specified by thread_id exists.
26

RETURN VALUE

28       Upon  successful completion, pthread_getcpuclockid() shall return zero;
29       otherwise, an error number shall be returned to indicate the error.
30

ERRORS

32       No errors are defined.

APPLICATION USAGE

40       The pthread_getcpuclockid() function is part  of  the  Thread  CPU-Time
41       Clocks option and need not be provided on all implementations.
42

RATIONALE

44       If  an  implementation  detects use of a thread ID after the end of its
45       lifetime, it is recommended that the function should fail and report an
46       [ESRCH] error.
47

FUTURE DIRECTIONS

49       None.
