MPI_Comm_call_errhandler - Passes the supplied error code to the
error handler assigned to a communicator
#include <mpi.h>
int MPI_Comm_call_errhandler(MPI_Comm comm, int errorcode)
USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_COMM_CALL_ERRHANDLER(COMM, ERRORCODE, IERROR)
INTEGER COMM, ERRORCODE, IERROR
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
- comm
- communicator with error handler (handle).
- errorcode
- error code (integer).
- IERROR
- Fortran only: Error status
(integer).
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.
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.
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.
