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++ func-
       tions 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.
