Open C Sockets Overview
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.
