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 pro-
cesses 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++ 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.
See the MPI man page for a full list of MPI error codes.
