Socket BSD API man pages

Socket BSD API man pages:

Sockets API:

• socket: establish socket interface
• gethostname: obtain hostname of system
• gethostbyname: returns a structure of type hostent for the given host name
• bind: bind a name to a socket
• listen: listen for connections on a socket
• accept: accept a connection on a socket
• connect: initiate a connection on a socket
• setsockopt: set a particular socket option for the specified socket.
• close: close a file descriptor
• shutdown: shut down part of a full-duplex connection

Interrogate a socket:

• select: synchronous I/O multiplexing
• FD_ZERO(), FD_CLR(), FD_SET(), FD_ISSET(): Set socket bit masks
• poll: check on the state of a socket in a set of sockets. The set can be tested to see if any socket can be written to, read from or if an error occurred.
• getsockopt: retrieve the current value of a particular socket option for the specified socket.

Read/Write:

• recv/recvfrom/recvmsg: Read socket
• send/sendto/sendmsg: Write socket

Convert:

• ntohl/htonl, ntohs/htons: convert values between host and network byte order
• inet_pton: Create a network address structure
• inet_ntop: Parse network address structures

Other supporting system calls:

• exit: Terminate process
• perror: Output explanation of an error code
• protocols: Network Protocols (see /etc/protocols)
