NAME
PAPI_get_thr_specific - Retrieve a pointer to a thread specific data structure.
SYNOPSIS
Detailed Description @par Prototype: int PAPI_get_thr_specific( int tag, void **ptr ); @param tag An identifier, the value of which is either PAPI_USR1_TLS or PAPI_USR2_TLS. This identifier indicates which of several data structures associated with this thread is to be accessed. @param ptr A pointer to the memory containing the data structure. @retval PAPI_OK @retval PAPI_EINVAL The @em tag argument is out of range. In C, PAPI_get_thr_specific PAPI_get_thr_specific will retrieve the pointer from the array with index @em tag. There are 2 user available locations and @em tag can be either PAPI_USR1_TLS or PAPI_USR2_TLS. The array mentioned above is managed by PAPI and allocated to each thread which has called PAPI_thread_init. There is no Fortran equivalent function. @par Example: int ret; HighLevelInfo *state = NULL; ret = PAPI_thread_init(pthread_self); if (ret != PAPI_OK) handle_error(ret); // Do we have the thread specific data setup yet? ret = PAPI_get_thr_specific(PAPI_USR1_TLS, (void *) &state); if (ret != PAPI_OK || state == NULL) { state = (HighLevelInfo *) malloc(sizeof(HighLevelInfo)); if (state == NULL) return (PAPI_ESYS); memset(state, 0, sizeof(HighLevelInfo)); state->EventSet = PAPI_NULL; ret = PAPI_create_eventset(&state->EventSet); if (ret != PAPI_OK) return (PAPI_ESYS); ret = PAPI_set_thr_specific(PAPI_USR1_TLS, state); if (ret != PAPI_OK) return (ret); } * See Also: PAPI_register_thread PAPI_thread_init PAPI_thread_id PAPI_set_thr_specific Author Generated automatically by Doxygen for PAPI from the source code.
