Detailed Description

C Interface:

#include <papi.h>
void PAPI_perror( const char *s );

Parameters

[in]

s

– Optional message to print before the string describing the last error message.

The routine PAPI_perror() produces a message on the standard error output, describing the last error encountered during a call to PAPI. If s is not NULL, s is printed, followed by a colon and a space. Then the error message and a new-line are printed.

Example:

int ret;
int EventSet = PAPI_NULL;
int native = 0x0;

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" );
   exit(1);
}
// Start counting
ret = PAPI_start(EventSet);
if (ret != PAPI_OK) handle_error(ret);
