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_Is_thread_main is called by a thread to find out whether the
|
|
caller is the main thread (that is, the thread that called MPI_Init or
|
|
MPI_Init_thread).
|
|
|
|
.SH ERRORS
|
|
.ft R
|
|
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.
|
|
.sp
|
|
See the MPI man page for a full list of MPI error codes.
