[libmicrohttpd] Re: libmicrohttpd 0.4.4 on Windows

[Christian Grothoff]

Hi!

That's interesting.  It could be that the FD_SETSIZE check does not apply on 
windows (certainly would be strange given that a small testcase produces such 
large file descriptor numbers), but I don't know enough about PlibC to say for 
sure.  On other systems, this is a check to make sure that we don't overflow 
the fd-set arrays when handling thousands of connections (or more, depending 
on what the OS limit is).  Nils Durner would probably be the person to ask how 
this should be addressed.

As far as your second question goes, that's also Nils' domain.

Best,

Christian
