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_Win_test is a one-sided MPI communication synchronization call, a
|
|
nonblocking version of MPI_Win_wait. It returns \fIflag = true\fP if
|
|
MPI_Win_wait would return, \fIflag = false\fP otherwise. The effect of return of MPI_Win_test with \fIflag = true\fP is the same as the effect of a return of MPI_Win_wait. If \fIflag = false\fP is returned, then the call has no visible effect.
|
|
.sp
|
|
Invoke MPI_Win_test only where MPI_Win_wait can be invoked. Once
|
|
the call has returned \fIflag = true\fP, it must not be invoked anew, until the window is posted anew.
|
|
|
|
|
|
.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_Win_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.
