swap_windowon

Usage

   #include <swap.h>
   void swap_windowoff(void);
   void swap_windowon(void);

Description

   These functions turn the Swap "window program output" facility on or off.
   When on, all output from the program that goes through stdout or stderr
   will be sent to a specified screen area (window). The window must have
   been previously defined  with a call to swap_window(), in which case

   swap_windowon() is only required if a previous call has been made to
   swap_windowoff().
