17.2.90. MPI_Errhandler_get

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'

  • 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.

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 handler. ERRORS

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.

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.
