| closesocket | This function closes an existing socket. |
| connect (Windows Sockets) | This function establishes a connection to a specified socket. |
| freeaddrinfo | This function frees address information that the getaddrinfo function dynamically allocates in its addrinfo structures. |
| getaddrinfo | This function provides protocol-independent translation from host name to address. |
| gethostbyaddr | This function retrieves the host information corresponding to a network address.
|
| gethostbyname | This function retrieves host information corresponding to a host name from a host database.
|
| gethostname | This function returns the standard host name for the local machine. |
| getnameinfo | This function provides name resolution from an address to the host name. |
| getpeername (Windows Sockets) | This function retrieves the name of the peer to which a socket is connected. |
| getsockname (Windows Sockets) | This function retrieves the local name for a socket. |
| getsockopt (Windows Sockets) | This function retrieves a socket option. |
| htonl | This function converts a u_long from host to TCP/IP network byte order, which is big-endian. |
| htons | This function converts a u_short from host to TCP/IP network byte order, which is big-endian. |
| inet_addr | This function converts a string containing an (Ipv4) Internet Protocol dotted address into a proper address for the in_addr structure. |
| inet_ntoa | This function converts an (Ipv4) Internet network address into a string in Internet standard dotted format. |
| ioctlsocket | This function controls the I/O mode of a socket. |
| listen | This function places a socket at a state where it is listening for an incoming connection. |
| ntohl | This function converts a u_long from TCP/IP network order to host byte order, which is little-endian on Intel processors. |
| ntohs | This function converts a u_short from TCP/IP network byte order to host byte order, which is little-endian on Intel processors. |
| recv | This function receives data from a connected socket. |
| recvfrom | This function receives a datagram and stores the source address. |
| select | This function determines the status of one or more sockets, waiting if necessary, to perform synchronous I/O. |
| send | This function sends data on a connected socket. |
| sendto | This function sends data to a specific destination. |
| sethostname | This function is used to register the host name on a network with the Windows Internet Naming Service (WINS). |
