WSK_SOCKET structure (wsk.h)
The WSK_SOCKET structure defines a socket object for a socket.
Syntax
typedef struct _WSK_SOCKET {
const VOID *Dispatch;
} WSK_SOCKET, *PWSK_SOCKET;
Members
Dispatch
A pointer to a constant provider dispatch structure. This structure is a dispatch table that contains pointers to a socket's functions. Depending on the WSK socket category of the socket, this pointer is a pointer to one of the following structures:
| Socket category | Dispatch table structure |
|---|---|
| Basic socket | WSK_PROVIDER_BASIC_DISPATCH |
| Listening socket | WSK_PROVIDER_LISTEN_DISPATCH |
| Datagram socket | WSK_PROVIDER_DATAGRAM_DISPATCH |
| Connection-oriented socket | WSK_PROVIDER_CONNECTION_DISPATCH |
| Stream socket | WSK_PROVIDER_STREAM_DISPATCH |
Remarks
The WSK subsystem allocates and fills in a WSK_SOCKET structure whenever a new socket is created. A WSK application receives a pointer to the WSK_SOCKET structure for a socket from the WSK subsystem in one of the following ways:
- The WSK application calls the WskSocket function to create a socket.
- The WSK application calls the WskSocketConnect function to create, bind, and connect a connection-oriented socket.
- The WSK application calls the WskAccept function to accept an incoming connection-oriented socket on a listening socket.
- The WSK subsystem calls the WSK application's WskAcceptEvent event callback function to notify the WSK application that an incoming connection-oriented socket has been accepted on a listening socket.
The WSK subsystem frees the memory for the WSK_SOCKET structure when the WSK application calls the WskCloseSocket function to close the socket.
