This mailing list is not here to help you with your own applications.
It is for discussion of the development of the Cygwin DLL and its
applications. There is a basic supposition that you know about
cygwin internals already. If you have to ask if something like
"cygwin_internal" will help you, you obviously aren't reading the
source code and you shouldn't be asking here.
Please use the main cygwin list.
