 *
 *	Header file for sequence generator functions
 *
 *  AUTHORS:
 *
 *	Dave Butenhof
 *
 *  CREATION DATE:
 *
 *	24 July 1989
 *
 *  MODIFICATION HISTORY:
 *
 *	001	Dave Butenhof	25 August 1989
 *		Add initialization code for convenience.
 *	002	Dave Butenhof	11 October 1989
 *		Convert to use internal mutex operations.
 *	003	Dave Butenhof	1 November 1989
 *		Remove circular header dependency with mutex.
 *	004	Dave Butenhof and Webb Scales	05 June 1991
 *		Conditionalize vacuous (forward) structure defs, since MIPS C
 *		V2.1 doesn't like (or, apparently, need).
