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

|
|
*
|
|
* WSCNTL_TCPIP_QUERY_INFO option is partially implemeted based
|
|
* on observing the behaviour of WsControl with an app in
|
|
* Windows 98. It is not fully implemented, and there could
|
|
* be (are?) errors due to incorrect assumptions made.
|
|
*
|
|
*
|
|
* WsControl returns WSCTL_SUCCESS on success.
|
|
* STATUS_BUFFER_TOO_SMALL is returned if the output buffer length
|
|
* (*pcbResponseInfoLen) is too small, otherwise errors return -1.
|
|
*
|
|
* It doesn't seem to generate errors that can be retrieved by
|
|
* WSAGetLastError().
