The following table shows the socket functions with a description of the purpose of each.

Programming element Description

accept (Windows Sockets)

This function permits an incoming connection attempt on a socket.

bind (Windows Sockets)

This function associates a local address with a socket.

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.

> [!NOTE] > The gethostbyaddr function has been deprecated by the introduction of the getnameinfo function. Developers who create Windows Sockets 2 applications are urged to use the getnameinfo function instead of the gethostbyaddr function.

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).

setsockopt (Windows Sockets)

This function sets a socket option.

shutdown

This function disables sends or receives on a socket.

socket (Windows Sockets)

This function creates a socket that is bound to a specific service provider.
