NAME

       MPI_Comm_call_errhandler  - Passes the supplied error code to the error
       handler assigned to a communicator

SYNTAX

C Syntax

       #include <mpi.h>
       int MPI_Comm_call_errhandler(MPI_Comm comm, int errorcode)

Fortran Syntax

       INCLUDE ’mpif.h’
       MPI_COMM_CALL_ERRHANDLER(COMM, ERRORCODE, IERROR)
            INTEGER   COMM, ERRORCODE, IERROR

C++ Syntax

       #include <mpi.h>
       void MPI::Comm::Call_errhandler(int errorcode) const

INPUT PARAMETER

       comm          communicator with error handler (handle).

       errorcode     error code (integer).

OUTPUT PARAMETERS

       IERROR        Fortran only: Error status (integer).

DESCRIPTION

       This function invokes the error handler assigned  to  the  communicator
       comm  with  the supplied error code errorcode. If the error handler was
       successfully called, the process is not aborted, and the error  handler
       returns, this function returns MPI_SUCCESS.

NOTES

       Users    should    note    that    the   default   error   handler   is
       MPI_ERRORS_ARE_FATAL.  Thus,  calling  this  function  will  abort  the
       processes in comm if the default error handler has not been changed.

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.

       See the MPI man page for a full list of MPI error codes.
