/* terminal.h - Craig Kelley - March 9, 1995 
 *
 * This library contains (and will contain more) useful procedures
 * to unclutter programs that deal with "raw" or "cbreak" terminals.
 * It will initialize the terminal (saving the old settings) and pass
 * an identifier to that terminal to the caller.  Then it will restore
 * the old values.  It's useful to trap the restore feature with signals,
 * so a global variable is defined (old_term) that contains the original
 * terminal settings.  The primary goal of this library is to make the
 * term stuff invisible, so that the programmer can deal with more
 * important things.
