NAME

       MPI_Add_error_code   -   Creates  a  new  error  code  associated  with
       errorclass

SYNTAX

C Syntax

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

Fortran Syntax

       INCLUDE ’mpif.h’
       MPI_ADD_ERROR_CODE(ERRORCLASS, ERRORCODE, IERROR)
            INTEGER  ERRORCLASS, ERRORCODE, IERROR

C++ Syntax

       #include <mpi.h>
       int MPI::Add_error_code(int errorclass, int* errorcode)

INPUT PARAMETER

       errorclass    MPI error class (integer).

OUTPUT PARAMETERS

       errorcode     Error code returned by an MPI routine  or  an  MPI  error
                     class (integer).

       IERROR        Fortran only: Error status (integer).

DESCRIPTION

       Creates  a  new  error  code associated with errorclass and returns its
       value in errorcode.

NOTES

       No function is provided to free error codes, as it is not expected that
       an application will create them in significant numbers.

       The value returned is always greater than or equal to MPI_ERR_LASTCODE.

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.
