SelectSaver(3)

NAME
     SelectSaver - save and restore selected file handle

SYNOPSIS
         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 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.
