PTHREAD_GETCPUCLOCKID(3P) POSIX Programmer's ManualPTHREAD_GETCPUCLOCKID(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
pthread_getcpuclockid — access a thread CPU-time clock (ADVANCED
REALTIME THREADS)
#include <pthread.h>
#include <time.h>
int pthread_getcpuclockid(pthread_t thread_id, clockid_t *clock_id);
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.
Upon successful completion, pthread_getcpuclockid() shall return
zero; otherwise, an error number shall be returned to indicate the
error.
No errors are defined.
The following sections are informative.
None.
The pthread_getcpuclockid() function is part of the Thread CPU-Time
Clocks option and need not be provided on all implementations.
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.
None.
