[libmicrohttpd] How to get fd numbers used by library

[Filip Svoboda - Netajo s.r.o.]

Hello,

I need to implement external poll() in my application using 
libmicrohttpd and I didn't find way to get out all file descriptor 
numbers used by the library.. I Know function:

MHD_get_fdset();

but it seems impossible to get out fd numbers from fd_set structure.

Is the only solution to call select() after my main poll() ?

Thank you for your time.
