Berkeley Sockets - Header Files

Header Files

The Berkeley socket interface is defined in several header files. The names and content of these files differ slightly between implementations. In general, they include:

Core BSD socket functions and data structures.
AF_INET and AF_INET6 address families and their corresponding protocol families PF_INET and PF_INET6. Widely used on the Internet, these include IP addresses and TCP and UDP port numbers.
PF_UNIX/PF_LOCAL address family. Used for local communication between programs running on the same computer. Not used on networks.
Functions for manipulating numeric IP addresses.
Functions for translating protocol names and host names into numeric addresses. Searches local data as well as DNS.

Famous quotes containing the word files:

    “The good husband finds method as efficient in the packing of fire-wood in a shed, or in the harvesting of fruits in the cellar, as in Peninsular campaigns or the files of the Department of State.”
    —Ralph Waldo Emerson (1803–1882)
