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\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);
