Return the clock ID of the CPU-time clock from a specified thread

Synopsis:

#include <sys/types.h>
#include <time.h>
#include <pthread.h>

extern int pthread_getcpuclockid( 
                         pthread_t id,
                         clockid_t* clock_id);

Arguments:

thread
The ID of the thread that you want to get the clock ID for, which you can get when you call pthread_create() or pthread_self().
clock_id
A pointer to a clockid_t object where the function can store the clock ID.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.
