PTHREAD_GETCPUCLOCKID(3) Linux Programmer's Manual PTHREAD_GETCPUCLOCKID(3)
NAME
pthread_getcpuclockid - retrieve ID of a thread's CPU time clock
SYNOPSIS
#include <pthread.h>
#include <time.h>
int pthread_getcpuclockid(pthread_t thread, clockid_t *clock_id);
Compile and link with -pthread.
DESCRIPTION
The pthread_getcpuclockid() function returns the clock ID for the CPU time clock of the thread thread.
RETURN VALUE
On success, this function returns 0; on error, it returns a nonzero error number.
ERRORS
ENOENT Per-thread CPU time clocks are not supported by the system.
ESRCH No thread with the ID thread could be found.
VERSIONS
This function is available in glibc since version 2.2.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).
+------------------------+---------------+---------+
|Interface | Attribute | Value |
+------------------------+---------------+---------+
|pthread_getcpuclockid() | Thread safety | MT-Safe |
+------------------------+---------------+---------+
CONFORMING TO
POSIX.1-2001, POSIX.1-2008.
NOTES
When thread refers to the calling thread, this function returns an identifier that refers to the same clock manipulated by clock_gettime(2)
and clock_settime(2) when given the clock ID CLOCK_THREAD_CPUTIME_ID.
EXAMPLE
The program below creates a thread and then uses clock_gettime(2) to retrieve the total process CPU time, and the per-thread CPU time con-
sumed by the two threads. The following shell session shows an example run:
$ ./a.out
Main thread sleeping
Subthread starting infinite loop
Main thread consuming some CPU time...
Process total CPU time: 1.368
Main thread CPU time: 0.376
Subthread CPU time: 0.992
