.SH DESCRIPTION
|
|
.ft R
|
|
MPI_Win_get_info returns a new info object containing the hints of
|
|
the window associated with
|
|
.IR win .
|
|
The current setting of all hints actually used by the system related
|
|
to this window is returned in
|
|
.IR info_used .
|
|
If no such hints exist, a handle to a newly created info object is
|
|
returned that contains no key/value pair. The user is responsible for
|
|
freeing info_used via MPI_Info_free.
|
|
.
|
|
.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.
