pthread_getcpuclockid —
get a clock measuring thread CPU time
#include
<pthread.h>
int
pthread_getcpuclockid(
pthread_t
thread,
clockid_t
*clock_id);
The
pthread_getcpuclockid() function allows
the calling thread to get a
clockid_t value
that measures the time spent by CPUs running in user or kernel mode on behalf
of the thread specified by
thread.
If successful,
pthread_getcpuclockid() will
return zero. Otherwise an error number will be returned to indicate the error.
pthread_getcpuclockid() will fail if:
-
-
- [
ESRCH]
- thread is an invalid thread ID.

The
pthread_getcpuclockid() function conforms
to
IEEE Std 1003.1-2008
(“POSIX.1”).
The
pthread_getcpuclockid() function first
appeared in IEEE Std 1003.1d-1999 (“POSIX.1d”) and has been
available since
