SelectSaver - save and restore selected file handleSYNOPSIS
use SelectSaver; { my $saver = new SelectSaver(FILEHANDLE); # FILEHANDLE is selected } # previous handle is selected { my $saver = new SelectSaver; # new handle may be selected, or not } # previous handle is selectedDESCRIPTION
A `SelectSaver' object contains a reference to the file handle that was selected when it was created. If its `new' method gets an extra parameter, then that parameter is selected; otherwise, the selected file handle remains unchanged. When a `SelectSaver' is destroyed, it re-selects the file handle that was selected when it was created.
