A.2 Header Files
A.2.1 Berkeley Header Files
A Windows Sockets supplier who provides a development kit to support the development of Windows Sockets applications must supply a set of vestigial header files with names that match a number of the header files in the Berkeley software distribution. These files are provided for source code compatibility only, and each consists of three lines:
#ifndef _WINSOCKAPI_
#include <winsock.h>
#endif
The header files provided for compatibility are:
netdb.h
arpa/inet.h
sys/time.h
sys/socket.h
netinet/in.h
The file winsock.h contains all of the type and structure definitions, constants, macros, and function prototypes used by the Windows Sockets specification. An application writer may choose to ignore the compatibility headers and include winsock.h in each source file.
A.2.2 Windows Sockets Header File - winsock.h
The winsock.h header file includes a number of types and definitions from the standard Windows header file windows.h. The windows.h in the Windows 3.0 SDK (Software Developer's Kit) lacks a #include guard, so if you need to include windows.h as well as winsock.h, you should define the symbol _INC_WINDOWS before #including winsock.h, as follows:
#include <windows.h>
#define _INC_WINDOWS
#include <winsock.h>
Users of the SDK for Windows 3.1 and later need not do this.
A Windows Sockets DLL vendor MUST NOT make any modifications to this header file which could impact binary compatibility of Windows Sockets applications. The constant values, function parameters and return codes, and the like must remain consistent across all Windows Sockets DLL vendors.
