usock -- UNIX domain sockets drivers

Description

These drivers are used as the transport mechanism, or more appropriately the interprocess communication mechanism, for processes communicating in the UNIX^® domain. Two drivers exist: one provides connectionless service and the other provides connection oriented service. Both the drivers are loopback-TLI streams drivers. The socket driver (see sock(7sock)) passes data from the user to the UNIX domain sockets drivers which in turn pass the data back to the socket driver as appropriate.

Files

/dev/ticlts: device interface to the connectionless loopback transport provider
/dev/ticots: device interface to the connection-oriented loopback transport provider
/dev/ticotsord: device interface to the connection-oriented loopback transport provider with orderly release

Notices

The systemwide number of UNIX domain sockets is controlled by the value of the third field (unit) in the file /etc/conf/sdevice.d/ticots. Changes to this file will not take effect until you rebuild and reboot the system as described in ``Rebuilding your system'' in Configuring system hardware.
