SelectSaver(3)	       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.
