Solaris X Window System Developer's Guide

Shared Memory Transport

The Solaris X server includes the Sun extension SUN_SME, Sun's implementation of a shared memory transport mechanism. This extension provides the capability of sending client requests to the server via shared memory. Shared memory is used for client requests only. Replies from the server and events are sent via the default transport mechanism. To enable this transport mechanism, set the DISPLAY environment variable to :x.y, where x is the display number, and y is the screen number, and set the environment variable XSUNTRANSPORT to shmem. The size of the segment can be set by setting the environment variable XSUNSMESIZE to the desired size in Kbytes. By default, XSUNSMESIZE is set to 64.
