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.

flag

If true, indicates request was canceled (logical).

.SH DESCRIPTION
|
|
.ft R
|
|
If \fIflag\fP is set to true, then a subsequent call to MPI_Test_cancelled(\fIstatus, flag\fP) will also return \fIflag\fP = true; otherwise it will return false.
|
|
|
|
.SH NOTES
|
|
.ft R
|
|
Users are advised not to reuse the status fields for values other than those for which they were intended. Doing so may lead to unexpected results when using the status object. For example, calling MPI_Get_elements may cause an error if the value is out of range, or it may be impossible to detect such an error. The \fIextra_state\fP argument provided with a generalized request can be used to return information that does not logically belong in \fIstatus\fP. Furthermore, modifying the values in a status set internally by MPI, such as MPI_Recv, may lead to unpredictable results and is strongly discouraged.
|
|
|
|
.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.
