pthread_getcpuclockid - access a thread CPU-time clock (ADVANCED REALTIME THREADS) SYNOPSIS
#include <pthread.h> #include <time.h> int pthread_getcpuclockid(pthread_t thread_id, clockid_t *clock_id); DESCRIPTION
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. RETURN VALUE
Upon successful completion, pthread_getcpuclockid() shall return zero; otherwise, an error number shall be returned to indicate the error. ERRORS
The pthread_getcpuclockid() function may fail if: ESRCH The value specified by thread_id does not refer to an existing thread. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
The pthread_getcpuclockid() function is part of the Thread CPU-Time Clocks option and need not be provided on all implementations. RATIONALE
None. FUTURE DIRECTIONS
None. SEE ALSO

Upon successful completion, pthread_getcpuclockid() shall return zero; otherwise, an error number shall be returned to indicate the error. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
The pthread_getcpuclockid() function is part of the Thread CPU-Time Clocks option and need not be provided on all implementations. RATIONALE
If an implementation detects use of a thread ID after the end of its lifetime, it is recommended that the function should fail and report an [ESRCH] error. FUTURE DIRECTIONS
None. SEE ALSO
