/* wscontrol.h
 *
 * This header file includes #defines, structure and type definitions,
 * and function declarations that support the implementation of the
 * (undocumented) Winsock 1 call WsControl.
 *
 * The functionality of WsControl was created by observing its behaviour
 * in Windows 98, so there are likely to be bugs with the assumptions
 * that were made.  A significant amount of help came from
 * http://tangentsoft.net/wskfaq/articles/wscontrol.html , especially the
 * trace by Thomas Divine (www.pcausa.net).
