MPI_Type_get_name(3OpenMPI)MPI_Type_get_name(3OpenMPI)NAME
MPI_Type_get_name - Gets the name of a data type.
SYNTAX C Syntax
#include <mpi.h>
int MPI_Type_get_name(MPI_Datatype type, char *type_name,
int *resultlen)
Fortran Syntax
INCLUDE 'mpif.h'
TYPE_GET_NAME(TYPE, TYPE_NAME, RESULTLEN, IERROR)
INTEGER TYPE, RESULTLEN, IERROR
CHARACTER*(*) TYPE_NAME
C++ Syntax
#include <mpi.h>
void MPI::Datatype::Get_name(char* type_name, int& resultlen)
const
INPUT PARAMETER
type Data type whose name is to be returned (handle).
OUTPUT PARAMETERS
type_name The name previously stored on the data type, or an empty string if not such name exists (string).
resultlen Length of returned name (integer).
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_Type_get_name returns the printable identifier associated with an MPI data type.
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.
# When the shell exits, append to the history file instead of overwriting it

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˘.

Hi all...
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)
