\fBExample:\fP
.RS 4
.PP
.nf
int ret;
int EventSet = PAPI_NULL;
int native = 0x0;
char error_str[PAPI_MAX_STR_LEN];
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK)
{
fprintf(stderr, "PAPI error %d: %s\\n", ret, PAPI_strerror(retval));
exit(1);
}
// Add Total Instructions Executed to our EventSet
ret = PAPI_add_event(EventSet, PAPI_TOT_INS);
if (ret != PAPI_OK)
{
PAPI_perror( "PAPI_add_event");
fprintf(stderr,"PAPI_error %d: %s\\n", ret, error_str);
