getsockname Gets the socket address of the speciﬁed socket.

getsockopt,

setsockopt

Gets, or sets, the options associated with a socket.

getpeername Gets the name of the peer socket connected to the

speciﬁed socket.

System Call Description

read Can be used to read data at stream or datagram

sockets just like recv or recvfrom , without the

beneﬁt of the recv ﬂags. Read offers implementation

independence; the descriptor can be for a ﬁle, a

socket or any other object.

write Can be used to write data from stream sockets (and

datagram sockets if you declare a default remote

socket address) just like send. Write offers

implementation independence; the descriptor can be

for a ﬁle, a socket or any other object.

close Deallocates socket descriptors. The last close can be

used to destroy a socket. Close does a graceful

disconnect or a hard close, depending on the

LINGER option. Refer to the sections on “Closing a

Socket.”
