Ws2def.h

This section contains kernel mode network driver topics for the Ws2def.h header. This header is included in the Windows SDK as it is also shared with user mode networking applications.

The Ws2def.h header contains definitions for the Winsock2 specification. It is included in Winsock2.h. User mode applications should include Winsock2.h rather than including Ws2def.h directly. Ws2def.h cannot be included by a module that also includes Winsock.h.

Important

This section's topics contains pages for definitions, macros, OIDs, status indications, and other data structures that are not part of network driver reference (structures, enumerations, functions, and callbacks).

For more information about network driver reference for this header, see Ws2def.h (reference).
