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
OpenBSD 5.4.
