### Death and Resurrection

The EDDMDEAD.C file contains the functions eddm_Death, and eddm_ Resurrection, which are used when switching to and from full-screen Windows **, DOS, or OS/2 sessions. The eddm_Death function handles the switch of the presentation display driver into the background. It switches the display to text mode, sets the drawing mode to software-drawing mode, and disables the bit map cache. The eddm_Resurrection function performs the inverse task. It switches the driver back into graphics mode, reloads the palette if needed, and invalidates the font cache.
