 +==== Description of closegraph ==== 
 +<code c>
 +closegraph deallocates all memory allocated by the graphics system, then
 +restores the screen to the mode it was in before you called initgraph.
 +(The graphics system deallocates memory, such as the drivers, fonts, and
 +an internal buffer, through a call to _graphfreemem.)
