PAPI_strerror (3) - Linux Manuals

NAME

PAPI_strerror -

Returns a string describing the PAPI error code.

SYNOPSIS

Detailed Description

C Interface:

#include <papi.h>

 char * PAPI_strerror( int errorCode );

Parameters:

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