NAME

MPI_Error_class - Converts an error code into an error class.

 

SYNTAX

 

C Syntax

#include <mpi.h>
int MPI_Error_class(int errorcode, int *errorclass)

 

Fortran Syntax

INCLUDE 'mpif.h'
MPI_ERROR_CLASS(ERRORCODE, ERRORCLASS, IERROR)
        INTEGER ERRORCODE, ERRORCLASS, IERROR 

 

C++ Syntax

#include <mpi.h>
int Get_error_class(int errorcode)

 

INPUT PARAMETER

errorcode
Error code returned by an MPI routine.

 

OUTPUT PARAMETERS

errorclass
Error class associated with errorcode.
IERROR
Fortran only: Error status (integer).

 

DESCRIPTION

The function MPI_Error_class maps each standard error code (error class) onto itself.

 

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.
