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.
