PAPI_thread_id - Get the thread identifier of the current thread.
@retval PAPI_EMISC is returned if there are no threads registered. @retval -1 is returned if the thread id function returns an error. This function returns a valid thread identifier. It calls the function registered with PAPI through a call to PAPI_thread_init(). unsigned long tid; if ((tid = PAPI_thread_id()) == (unsigned long int)-1 ) exit(1); printf("Initial thread id is: %lu0, tid ); * See Also: PAPI_thread_init
