This chapter describes, in alphabetic order, addenda to standard items (structures and functions) of the Windows Sockets applications programming interface. Each description contains the syntax, purpose, and addendum for the item. Only items with addenda to the Windows Sockets Version 1.1 specification appear. Refer to that specification for additional details about the included items, as well as information about the unchanged items.
The syntax for each item appears in C-language format. In your C-language source files, spell the item names exactly as shown, and use parameters in the given order. You can use these items in your applications by placing the directive
#include <wsvv.h>
at the beginning of your source files.
