SYNTAX

C Syntax

#include <mpi.h>
int MPI_Add_error_string(int errorcode, const char *string)

Fortran Syntax

INCLUDE ’mpif.h’
MPI_ADD_ERROR_STRING(ERRORCODE, STRING, IERROR)
        INTEGER         ERRORCODE, IERROR
        CHARACTER*(*)   STRING

C++ Syntax

#include <mpi.h>
void MPI::Add_error_string(int errorcode, const char* string)

INPUT PARAMETERS

errorcode MPI error class, or an error code returned by an MPI routine (integer).
string Text that corresponds to the error code or class (string).

OUTPUT PARAMETER

IERROR Fortran only: Error status (integer).

DESCRIPTION

This routine associates an error string with an error code or class. Calling MPI_Add_error_string for an error code or class that already has an associated error string will replace the old string with the new one. It is erroneous to call MPI_Add_error_string for an error value not generated via MPI_Add_error_class or MPI_Add_error_code (e.g., an error code or class with a value not greater than MPI_LAST_ERRCODE).

ERRORS

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI::Exception object.

Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
