MPI_Errhandler_get(3OpenMPI) MPI_Errhandler_get(3OpenMPI)
NAME
MPI_Errhandler_get - Gets the error handler for a communicator -- use
of this routine is deprecated.
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Errhandler_get(MPI_Comm comm, MPI_Errhandler *errhandler)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_ERRHANDLER_GET(COMM, ERRHANDLER, IERROR)
INTEGER COMM, ERRHANDLER, IERROR
INPUT PARAMETER
comm Communicator to get the error handler from (handle).
OUTPUT PARAMETERS
errhandler
MPI error handler currently associated with communicator
(handle).
IERROR Fortran only: Error status (integer).
DESCRIPTION
Note that use of this routine is deprecated as of MPI-2. Please use
MPI_Comm_get_errhandler instead.
This deprecated routine is not available in C++.
Returns in errhandler (a handle to) the error handler that is currently
associated with communicator comm.
Example: A library function may register at its entry point the current
error handler for a communicator, set its own private error handler for
this communicator, and restore before exiting the previous error han-
dler.
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++ func-
tions 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.
