Re: [Openslp-users] Cannot get OpenSLP to work on Windows 7

[Nick W. <ne...@wi...>]

What is WSAGetLastError returning when you see the recvfrom error?

And as far as the first patch goes, I believe Jon's intent was to check for
an empty string, not just a null pointer.  So I would try:

if ((cmdline->scopes != 0) && (*cmdline->scopes != 0))
       SLPSetProperty("net.slp.useScopes", cmdline->scopes);
