.SH NAME
PAPI_get_thr_specific \-
.PP
Retrieve a pointer to a thread specific data structure\&.
.SH SYNOPSIS
.br
.PP
.SH "Detailed Description"
.PP
.PP
.nf
@par Prototype:
\#include <papi.h> @n
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:
.fi
.PP
.PP
.nf
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);
