Hi all,
I have a bit of a problem. Essentially, the problem is that Java 1.4 is buggy, it includes winsock.h, but then proceeds to use winsock2. That wouldn't be an issue, except that my app uses multicast sockets, and for reasons known only to Redmond they decided to change the values of some of the multicast socket option constants.
Java, therefore, passes in the winsock1 values to winsock2. Windows apparently can deal with this just fine (well, the appw works), despite there being no obvious way to remap them, both IP_MULTICAST_IF and IP_HDRINCL which both == 2 in different winsock versions would be valid at once on XP/2003 for instance.
Marcus, I know you took a stab at implementing multicast support once, so if you have any tips that'd be appreciated.
If anybody knows a way you might be able to detect that a program is using the wrong headers for the winsock2 dll, please let me know.
thanks -mike
