PAPI_perror (3)

C Interface:

#include <papi.h>

void PAPI_perror( char *s );

Parameters:

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, 
*     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);
*
