8wxTempFileOutputStream is an output stream based on \helpref{wxTempFile}{wxtempfile}. It
9provides a relatively safe way to replace the contents of the
10existing file.

31Associates wxTempFileOutputStream with the file to be replaced and opens it. You should use 
32\helpref{IsOk}{wxstreambaseisok} to verify if the constructor succeeded.
33
34Call \helpref{Commit()}{wxtempfileoutputstreamcommit} or \helpref{Close()}{wxoutputstreamclose} to
35replace the old file and close this one. Calling \helpref{Discard()}{wxtempfileoutputstreamdiscard} 
36(or allowing the destructor to do it) will discard the changes.

43Validate changes: deletes the old file of the given name and renames the new
44file to the old name. Returns {\tt true} if both actions succeeded. If {\tt false} is
45returned it may unfortunately mean two quite different things: either that
46either the old file couldn't be deleted or that the new file couldn't be renamed
47to the old name.
