Joe,

In your code of Feb 14 2003:

http://groups-beta.google.com/group/comp.programming.threads/tree/browse_frm/thread/dec4902c7f6cd24a/09cf7867c13854a7?rnum=21&hl=en&_done=%2Fgroup%2Fcomp.programming.threads%2Fbrowse_frm%2Fthread%2Fdec4902c7f6cd24a%3F#doc_1546cac7cd68c5fc

I don't know what algorithm you are actually using. Is it documented 
somewhere or did you make it up?

I need to educate myself because I don't fully understand the roles of 
the following items:

  typedef struct waitset_tt {
         struct waitset_tt *next;
         LONG refCount;
         ^^^^^^^^^^^^^^

	LONG waitCount;

         LONG deferCount;
	^^^^^^^^^^^^^^^^

         HANDLE sem;

} waitset_t;

  typedef struct {
         qfree_t *fq;

         waitset_t *waitset1;
	^^^^^^^^^^^^^^^^^^^^

         waitset_t *waitset2;
         ^^^^^^^^^^^^^^^^^^^^

         CRITICAL_SECTION cs;

         condattr_t attr;
} cond_t;

Could you point me to some reading materials or put me in the right 
direction in any way?
