NAME¶
MPI_Comm_call_errhandler - Passes the supplied error code to the error
handler assigned to a communicator
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
- 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.
