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 corresponding
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 REAL-
TIME 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.
