Following are the generic functions for socket interface such as sending and receiving messages from a socket.

• connect -- Initiates a connection on a socket
• getpeername -- Gets name of connected peer socket
• listen -- Listens for connections on a socket
• recv -- Receives a message from a socket
• send -- Sends a message from a socket
• recvfrom -- Receives a message from a socket
• sendto -- Sends a message from a socket
• shutdown -- Brings the system down
• socket -- Creates an endpoint for communication
• bind -- Bash built-in commands
• getsockname -- Gets socket name
• getsockopt -- Gets options on sockets
• setsockopt -- Sets options on sockets

And following are some of the namespaces used in Open C Socket Interface:

• if_freenameindex -- Free memory allocated by if_nameindex
• if_indextoname -- Maps a network interface index to its corresponding name
• if_nameindex -- Returns all network interface names and indexes
• if_nametoindex -- Maps a network interface name to its corresponding index

A 3rd-party application needs the NetworkServices capabilities in order to use socket interface functions.

libc.lib should be linked while using the above functions and sys/socket.h should be included.
