Note:

The XSH specification contains the basic definition of this interface. The following additional information pertains to Sockets.

DESCRIPTION

If fildes refers to a socket, close() causes the socket to be destroyed. If the socket is connection-mode, and the SO_LINGER option is set for the socket with non-zero linger time, and the socket has untransmitted data, then close() will block for up to the current linger interval until all data is transmitted.
