MPI_Comm_set_errhandler(3OpenMPI)MPI_Comm_set_errhandler(3OpenMPI)NAME
MPI_Comm_set_errhandler - Attaches a new error handler to a communicator.
SYNTAX C Syntax
#include <mpi.h>
int MPI_Comm_set_errhandler(MPI_Comm comm,
MPI_Errhandler errhandler)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_COMM_SET_ERRHANDLER(COMM, ERRHANDLER, IERROR)
INTEGER COMM, ERRHANDLER, IERROR
C++ Syntax
#include <mpi.h>
void MPI::Comm::Set_errhandler(const MPI::Errhandler& errhandler)
INPUT /OUTPUT PARAMETER
comm Communicator (handle).
OUTPUT PARAMETERS
errhandler
New error handler for communicator (handle).
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_Comm_set_errhandler attaches a new error handler to a communicator. The error handler must be either a predefined error handler or an
error handler created by a call to MPI_Comm_create_errhandler. This call is identical to MPI_Errhandler_set, the use of which is depre-
cated.
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.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.

Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).

This is purely a fun project to see if it is possible in PURE... (3 Replies)
