pthread_getcpuclockid - access a thread CPU-time clock (ADVANCED REALTIME THREADS)
[THR TCT] #include <pthread.h>
int pthread_getcpuclockid(pthread_t thread_id, clockid_t *clock_id);
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.
Upon successful completion, pthread_getcpuclockid() shall return zero; otherwise, an error number shall be returned to indicate the error.
The pthread_getcpuclockid() function may fail if:
- The value specified by thread_id does not refer to an existing thread.
The pthread_getcpuclockid() function is part of the Thread CPU-Time Clocks option and need not be provided on all implementations.
