Version 7.1.0.0                                  Thu Dec 14 2023                        PAPI_set_thr_specific(3)

Prototype:
           #include <papi.h>
            int PAPI_set_thr_specific(inttag,void*ptr);

       Parameterstag 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.
           ptr A pointer to the memory containing the data structure.

       ReturnvaluesPAPI_OKPAPI_EINVAL The tag argument is out of range.

       In C, PAPI_set_thr_specific will save ptr into an array indexed by tag. There are 2 user available
       locations and 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.

       Example:

           int ret;
           RateInfo *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 = (RateInfo *) malloc(sizeof(RateInfo));
               if (state == NULL) return (PAPI_ESYS);
               memset(state, 0, sizeof(RateInfo));
               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);
           }
