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

36Associates wxTempFileOutputStream with the file to be replaced and opens it. You should use
37\helpref{IsOk}{wxstreambaseisok} to verify if the constructor succeeded.
38
39Call \helpref{Commit()}{wxtempfileoutputstreamcommit} or \helpref{Close()}{wxoutputstreamclose} to
40replace the old file and close this one. Calling \helpref{Discard()}{wxtempfileoutputstreamdiscard}
41(or allowing the destructor to do it) will discard the changes.

48Validate changes: deletes the old file of the given name and renames the new
49file to the old name. Returns {\tt true} if both actions succeeded. If {\tt false} is
50returned it may unfortunately mean two quite different things: either that
51either the old file couldn't be deleted or that the new file couldn't be renamed
52to the old name.

59Discard changes: the old file contents are not changed, the temporary file is
60deleted.
