Winsock Functions

This section provides a comprehensive reference for the Windows Sockets API (Winsock) functions. These functions enable applications to communicate over a network using the TCP/IP protocol suite and other network protocols.

Core Functions

• accept - Accepts a connection on a socket.
• bind - Associates a local address with a socket.
• closesocket - Closes an existing socket.
• connect - Establishes a connection to a remote socket.
• getaddrinfo - Retrieves address information for a specified host and service.
• gethostname - Retrieves the standard host name for the current computer.
• getpeername - Retrieves the name of the remote station connected to a socket.
• getsockname - Retrieves the current name as assigned to a socket.
• htonl - Converts a 32-bit quantity from host byte order to network byte order.
• htons - Converts a 16-bit quantity from host byte order to network byte order.
• inet_addr - Converts an IPv4 address string to its binary form.
• inet_ntoa - Converts an IPv4 address in binary form to its ASCII string representation.
• ioctlsocket - Sets or retrieves the nonblocking mode of a socket.
• listen - Puts a socket into a state where it listens for incoming connection requests.
• ntohl - Converts a 32-bit quantity from network byte order to host byte order.
• ntohs - Converts a 16-bit quantity from network byte order to host byte order.
• recv - Receives data from a connected socket.
• send - Sends data on a connected socket.
• socket - Creates a socket that is bound to a specific transport service provider.

Session Management Functions

• WSAAccept - Accepts a connection on a specified socket.

• getservbyport - Retrieves service information by port number.
• gai_strerror - Returns a string describing an address information error.
• inet_ntop - Converts an IP address structure to a string.
• inet_pton - Converts an IP address string to a structure.
• setsockopt - Sets socket options.
• getsockopt - Retrieves socket options.
• select - Monitors sockets for readiness.
• WSAAsyncSelect - Enables asynchronous network event notification.
• WSAAsyncGetAddrInfo - Asynchronously retrieves address information.
• WSAEnumNetworkEvents - Enumerates network events.
