This commit contains the following changes: The C++ bindings were removed from the standard in MPI-3.0. This commit removes the entirety of the C++ bindings as well as the support configury. Removes all references to C++ from the man pages. This includes the bindings themselves, all references to what C++ bindings return, all not-available comments, and differences between C++ and other language bindings. If the user passes --enable-mpi-cxx, --enable-mpi-cxx-seek, or --enable-cxx-exceptions, print a warning message an abort configure.

.SH DESCRIPTION
|
|
.ft R
|
|
The MPI_File_get_view routine returns the process's view of the data
|
|
in the file. The current values of the displacement, etype, and
|
|
filetype are returned in
|
|
.I disp,
|
|
.I etype,
|
|
and
|
|
.I filetype,
|
|
respectively.
|
|
.sp
|
|
The MPI_File_get_view interface allows the user to pass a data-representation string via the \fIdatarep\fP argument.
|
|
|
|
.SH FORTRAN 77 NOTES
|
|
.ft R
|
|
The MPI standard prescribes portable Fortran syntax for
|
|
the \fIDISP\fP argument only for Fortran 90. FORTRAN 77
|
|
users may use the non-portable syntax.
|
|
.sp
|
|
.nf
|
|
INTEGER*MPI_OFFSET_KIND \fIDISP\fP
|
|
.fi
|
|
.sp
|
|
where MPI_OFFSET_KIND is a constant defined in mpif.h
|
|
and gives the length of the declared integer in bytes.
|
|
|
|
.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.
|
|
.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.
