Hi Mary,

Welcome to proton development!

Regarding your pipe issue, please see the pn_socket_pair function in
the QPID-4181 patch.

I think you can use that with WSAPoll, but if the implementation in
driver.c with select() is easier to just copy, you might as well use
that.  Use of WSAPoll or select will be temporary anyway and be mostly
useful to bootstrap the serious porting work until IO completion ports
can be implemented.  QPID-4181 is certainly stale, but it ran the
proton-test suite on Windows.

If you wish to discuss approaches to the VLA issue, feel free to post
some pseudo-code in the context of a JIRA.  If shouldn't be necessary
to wait until you have a whole patch to get some feedback on the
course you are taking.

Cliff
