22 /* FIXME: This hack is fixing a problem in WsControl. When we call socket(),
23 * it will call into ws2_32's WSOCK32_socket (because of the redirection in
24 * our own .spec file).
25 * The problem is that socket() is predefined in a linux system header that
26 * we are including, which is different from the WINE definition.
27 * (cdecl vs. stdapi). The result is stack corruption.
28 * Furthermore WsControl uses Unix macros and types. This forces us to include
29 * the Unix headers which then conflict with the winsock headers. This forces
30 * us to use USE_WS_PREFIX but then ioctlsocket is called WS_ioctlsocket,
31 * which causes link problems. The correct solution is to implement
32 * WsControl using calls to WSAIoctl. Then we should no longer need to use the
33 * Unix headers. This would also have the advantage of reducing code
35 * Until that happens we need this ugly hack.

93 * WsControl (WSOCK32.1001)
95 * WsControl seems to be an undocumented Win95 function. A lot of

98 * From: "Peter Rindfuss" <rindfuss-s@medea.wz-berlin.de>
101 * WSCNTL_TCPIP_QUERY_INFO option is partially implemeted based
102 * on observing the behaviour of WsControl with an app in
103 * Windows 98. It is not fully implemented, and there could
104 * be (are?) errors due to incorrect assumptions made.
107 * WsControl returns WSCTL_SUCCESS on success.
108 * STATUS_BUFFER_TOO_SMALL is returned if the output buffer length
109 * (*pcbResponseInfoLen) is too small, otherwise errors return -1.
111 * It doesn't seem to generate errors that can be retrieved by
