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

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_ADD_ERROR_CODE(ERRORCLASS, ERRORCODE, IERROR)
            INTEGER  ERRORCLASS, ERRORCODE, IERROR

Fortran 2008 Syntax

       USE mpi_f08
       MPI_Add_error_code(errorclass, errorcode, ierror)
            INTEGER, INTENT(IN) :: errorclass
            INTEGER, INTENT(OUT) :: errorcode
            INTEGER, OPTIONAL, INTENT(OUT) :: 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.
