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.
