Return a string for a given error code


#include "mpi.h"
int MPI_Error_string( errorcode, string, resultlen )
int  errorcode, *resultlen;
char *string;

Input Parameters

Error code returned by an MPI routine or an MPI error class

Output Parameter

string Text that corresponds to the errorcode
resultlen Length of string

Notes: Error codes are the values return by MPI routines (in C) or in theierr argument (in Fortran). These can be converted into error classeswith the routine MPI_Error_class.

Notes for Fortran

All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK) havean additional argument ierr at the end of the argument list. ierris an integer and has the same meaning as the return value of the routinein C. In Fortran, MPI routines are subroutines, and are invoked with thecall statement.

All MPI objects (e.g., MPI_Datatype, MPI_Comm) are of type INTEGERin Fortran.
