LMAO, I agree.  But, doesn't that assume that the programmer actually
knows how to program efficiently?  I mean wouldn't it be more efficient
for someone that knows what efficient is to do this internally?

Oh, I was referring to the windows docs.  I guess they are completely
different.  I can definitely see why that would be efficient now.  After
all, an fd_set in eCos is only an array of integer masks.  Bit
manipulation is much faster than going through an array of SOCKETs.

eCos fd_set
typedef	struct fd_set {
	fd_mask	fds_bits[__howmany(FD_SETSIZE, __NFDBITS)];
} fd_set;

windows fd_set (LMAO, they suck)
typedef struct fd_set {
  u_int    fd_count;                 // how many are SET? 
  SOCKET   fd_array[FD_SETSIZE];     // an array of SOCKETs 
} fd_set;


And, infact windows does increment an fdcount! :) LOL
