NAME

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

SYNOPSIS

16       #include <pthread.h>
17       #include <time.h>
18
19       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       The pthread_getcpuclockid() function may fail if:
33
34       ESRCH  The value specified by thread_id does not refer to  an  existing
35              thread.
