Perl Programmers Reference Guide SelectSaver(3) NAME SelectSaver - save and restore selected file handle SYNOPSIS use SelectSaver; { my $saver = SelectSaver->new(FILEHANDLE); # FILEHANDLE is selected } # previous handle is selected { my $saver = SelectSaver->new; # new handle may be selected, or not } # previous handle is selected DESCRIPTION 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.
