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
|
|
MPI_File_get_atomicity returns the current consistency semantics for
|
|
data access operations on the set of file handles created by one
|
|
collective MPI_File_open. If \fIflag\fP is
|
|
.I true,
|
|
atomic mode is currently enabled; if
|
|
.I flag
|
|
is
|
|
.I false,
|
|
nonatomic mode is currently enabled.
|
|
|
|
.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.
