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

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

Fortran 2008 Syntax

       USE mpi_f08
       MPI_Comm_call_errhandler(comm, errorcode, ierror)
            TYPE(MPI_Comm), INTENT(IN) :: comm
            INTEGER, INTENT(IN) :: errorcode
            INTEGER, OPTIONAL, INTENT(OUT) :: 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.
