PAPI_strerror Class Reference

Returns a string describing the PAPI error code. More...

Detailed Description

C Interface:

#include <papi.h>
char * PAPI_strerror( int errorCode );

Parameters:

[in]

code

-- the error code to interpret

Return values:

*error	-- a pointer to the error string.
NULL	-- the input error code to PAPI_strerror() is invalid.

PAPI_strerror() returns a pointer to the error message corresponding to the error code code. If the call fails the function returns the NULL pointer. This function is not implemented in Fortran.

Example:

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