pthread_getcpuclockid(pthread_t thread, clockid_t *clock_id);

The pthread_getcpuclockid() function retrieves the clock_id for the specified thread.

The clock_gettime(2) function can be used with the returned clock_id to retrieve LWP times.

On success the pthread_getcpuclockid() function returns 0, placing the requested clock_id in the argument. Otherwise an error number will be returned.

These functions fail if:
[]
clock_id points outside the process's allocated address space.
