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 function MPI_Topo_test returns the type of topology that is assigned to a communicator.
|
|
.sp
|
|
The output value \fItop_type\fP is one of the following:
|
|
.sp
|
|
.nf
|
|
MPI_GRAPH graph topology
|
|
MPI_CART Cartesian topology
|
|
MPI_DIST_GRAPH distributed graph topology
|
|
MPI_UNDEFINED no topology
|
|
|
|
.fi
|
|
.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. 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.
