Detailed Description

The TWinSockDll class encapsulates the WinSock DLL (WINSOCK.DLL).

It provides an easy method to dynamically test for the availability of the DLL and bind to its exported functions at runtime. By using the TWinSockDll class instead of direct calls to the WinSock DLL, ObjectWindows applications can provide the appropriate behaviour when running in an environment where the DLL is not available.

Each data member of the TWinSockDll class corresponds to the API with a similar name exposed by the WinSock DLL. For example, TWinSockDll::WSAStartup corresponds to the WSAStartup API exported by the WinSock DLL.

For more information about the members, consult the documentation about the corresponding API exposed by the WinSock DLL.
