mswsock.h header
This header is used by Windows Sockets 2. For more information, see:
mswsock.h contains the following programming interfaces:
Functions
| AcceptEx The AcceptEx function (mswsock.h) accepts a new connection, returns the local and remote address, and receives the first block of data sent by the client application. |
| GetAcceptExSockaddrs The GetAcceptExSockaddrs function (mswsock.h) parses data obtained from a call to the AcceptEx function and passes local and remote addresses to a sockaddr structure. |
| TransmitFile The TransmitFile function (mswsock.h) transmits file data over a connected socket handle. |
| WSARecvEx The WSARecvEx function (mswsock.h) receives data from a connected socket or a bound connectionless socket. |
Callback functions
| LPFN_CONNECTEX The ConnectEx function establishes a connection to a specified socket, and optionally sends data once the connection is established. |
| LPFN_DISCONNECTEX Closes a connection on a socket, and allows the socket handle to be reused.Note This function is a Microsoft-specific extension to the Windows Sockets specification. |
| LPFN_RIOCLOSECOMPLETIONQUEUE Closes an existing completion queue used for I/O completion notification by send and receive requests with the Winsock registered I/O extensions. |
| LPFN_RIOCREATECOMPLETIONQUEUE Creates an I/O completion queue of a specific size for use with the Winsock registered I/O extensions. |
| LPFN_RIOCREATEREQUESTQUEUE Creates a registered I/O socket descriptor using a specified socket and I/O completion queues for use with the Winsock registered I/O extensions. |
| LPFN_RIODEQUEUECOMPLETION Removes entries from an I/O completion queue for use with the Winsock registered I/O extensions. |
| LPFN_RIODEREGISTERBUFFER Deregisters a registered buffer used with the Winsock registered I/O extensions. |
| LPFN_RIONOTIFY Registers the method to use for notification behavior with an I/O completion queue for use with the Winsock registered I/O extensions. |
| LPFN_RIORECEIVE Receives network data on a connected registered I/O TCP socket or a bound registered I/O UDP socket for use with the Winsock registered I/O extensions. |
| LPFN_RIORECEIVEEX Receives network data on a connected registered I/O TCP socket or a bound registered I/O UDP socket with additional options for use with the Winsock registered I/O extensions. |
| LPFN_RIOREGISTERBUFFER Registers a RIO_BUFFERID, a registered buffer descriptor, with a specified buffer for use with the Winsock registered I/O extensions. |
| LPFN_RIORESIZECOMPLETIONQUEUE Resizes an I/O completion queue to be either larger or smaller for use with the Winsock registered I/O extensions. |
| LPFN_RIORESIZEREQUESTQUEUE Resizes a request queue to be either larger or smaller for use with the Winsock registered I/O extensions. |
| LPFN_RIOSEND Sends network data on a connected registered I/O TCP socket or a bound registered I/O UDP socket for use with the Winsock registered I/O extensions. |
| LPFN_RIOSENDEX Sends network data on a connected registered I/O TCP socket or a bound registered I/O UDP socket with additional options for use with the Winsock registered I/O extensions. |
| LPFN_TRANSMITPACKETS Transmits in-memory data or file data over a connected socket. |
| LPFN_WSARECVMSG *LPFN_WSARECVMSG* is a function pointer type. You implement a matching WSARecvMsg callback function in your app. The system uses your callback function to transmit to you in-memory data, or file data, over a connected socket. |
Structures
| RIO_EXTENSION_FUNCTION_TABLE Contains information on the functions that implement the Winsock registered I/O extensions. |
| RIO_NOTIFICATION_COMPLETION Specifies the method for I/O completion to be used with a RIONotify function for sending or receiving network data with the Winsock registered I/O extensions. |
| TRANSMIT_FILE_BUFFERS The TRANSMIT_FILE_BUFFERS structure (mswsock.h) specifies data to be transmitted before and after file data during a TransmitFile function file transfer operation. |
| TRANSMIT_PACKETS_ELEMENT Specifies a single data element to be transmitted by the TransmitPackets function. |
Enumerations
| RIO_NOTIFICATION_COMPLETION_TYPE Specifies the type of completion queue notifications to use with the RIONotify function when sending or receiving data using the Winsock registered I/O extensions. |
