This merges the branch containing the revamped build system based around converting autogen from a bash script to a Perl program. Jeff has provided emails explaining the features contained in the change. Please note that configure requirements on components HAVE CHANGED. For example. a configure.params file is no longer required in each component directory. See Jeff's emails for an explanation. This commit was SVN r23764.

.SH DEPRECATED TYPE NAME NOTE

.ft R
|
|
MPI-2.2 deprecated the MPI_File_errhandler_fn and
|
|
MPI::file::Errhandler_fn types in favor of
|
|
MPI_File_errhandler_function and MPI::File::Errhandler_function,
|
|
respectively. Open MPI supports both names (indeed, the _fn names are
|
|
typedefs to the _function names).

|
|
User-defined error handling procedure (function).

.SH OUTPUT PARAMETERS
|

|
|
errhandler
|
|
MPI error handler (handle).
|

|
|

|

IERROR
|

Fortran only: Error status (integer).
|
|

|
.SH DESCRIPTION
|
|
.ft R
|
|
Registers the user routine \fIfunction\fP for use as an MPI exception handler. Returns in errhandler a handle to the registered exception handler.
|
|
.sp
|
|
In the C language, the user routine \fIfunction\fP should be a C function of type MPI_File_errhandler_function, which is defined as
|
|
.sp
|
|
.nf
|
|
typedef void (MPI_File_errhandler_function)(MPI_File *, int *,
|
|
\&...);
|
|
.fi
|
|
.sp
|
|
The first argument to \fIfunction\fP is the file in use. The second is the error code
|
|
to be returned by the MPI routine that raised the error.
|
|
.sp
|
|
In the Fortran language, the user routine should be of the form:
|
|
.sp
|
|
.nf
|
|
SUBROUTINE FILE_ERRHANDLER_FUNCTION(FILE, ERROR_CODE, ...)
|
|
INTEGER FILE, ERROR_CODE
|
|
.fi
|
|
.sp
|
|
In C++, the user routine \fIfunction\fP should be of the form:
|
|
.sp
|
|
.nf
|
|
typedef void MPI::File::Errhandler_function(MPI::File &, int *,
|
|
...);
|
|
.fi
|
|
.sp
|
|
|
|
.SH 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.
|
|
.sp
|
|
Before the error value is returned, the current MPI error handler is
|
|
called. For MPI I/O function errors, the default error handler is set to MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
