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

83 * Subject: Re: WSOCK32.DLL WsControl Exported Function
84 * From: "Peter Rindfuss" <rindfuss-s@medea.wz-berlin.de>
87 * The WSCNTL_TCPIP_QUERY_INFO option is partially implemented based
88 * on observing the behaviour of WsControl with an app in
89 * Windows 98. It is not fully implemented, and there could
90 * be (are?) errors due to incorrect assumptions made.
93 * WsControl returns WSCTL_SUCCESS on success.
94 * ERROR_LOCK_VIOLATION is returned if the output buffer length
95 * (*pcbResponseInfoLen) is too small. This is an unusual error code, but
96 * it matches Win98's behavior. Other errors come from winerror.h, not from
97 * winsock.h. Again, this is to match Win98 behavior.

627 * WSARecvEx (WSOCK32.1107)
629 * WSARecvEx is a Microsoft specific extension to winsock that is identical to recv
630 * except that has an in/out argument call flags that has the value MSG_PARTIAL ored
631 * into the flags parameter when a partial packet is read. This only applies to
632 * sockets using the datagram protocol. This method does not seem to be implemented
633 * correctly by microsoft as the winsock implementation does not set the MSG_PARTIAL
634 * flag when a fragmented packet arrives.
