SO_OPENTYPE

Thu Dec 13 21:21:52 CST 2001

I have an app that calls getsockopt(INVALID_SOCKET, SOL_SOCKET,
SO_OPENTYPE, etc.).  This is a Windows-specific socket option that
globally determines the nature of all subsequently created sockets. 
According to MS's documentation, the socket parameter is unused for
SO_OPENTYPE, but the current implementation in Wine does require a valid
socket.  I created a patch to handle SO_OPENTYPE separately in
get/setsockopt.  Right now, it will just get and set a global variable,
but nothing else in the code actually depends on its value.  It's 
supposed to affect whether new sockets use overlapped I/O or not, but I
don't think Wine currently supports overlapped on sockets anyway. 

The patch consists of a small change to winsock.h to add the necessary
public defines and a couple extra checks in socket.c. 

Changelog:
  Paul Rupe <prupe at nc.rr.com>
  Very simple support for SO_OPENTYPE in getsockopt and setsockopt.
