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.
