Problems with PAPI_event_name_to_code function

[adiazpon]

Hi all,

Im trying to use PAPI_event_name_to_code function and I am having some problems.

This is the code I am using

Code: Select all

int*  counter_translated;
PAPI_event_name_to_code("PAPI_L2_TCM",counter_translated);
printf("code=%x\n", counter_translated);
PAPI_add_event(EventSet, *counter_translated);


The result is

Code: Select all

code=0
Segmentation fault (core dumped)


I have been trying with other counters and I have the same problem. The pointer is pointing to null (=0) afther the execution.

Does anyone see anything wrong?

Thanks.

PAPI_event_name_to_code("PAPI_L2_TCM",counter_translated);
printf("code=%x\n", counter_translated);
PAPI_add_event(EventSet, *counter_translated);


Your code should be:

Code: Select all

int  counter_translated;
PAPI_event_name_to_code("PAPI_L2_TCM",&counter_translated);
printf("code=%x\n", counter_translated);
PAPI_add_event(EventSet, *counter_translated);
