intro - Introduction to special files
Section 7 describes the special files, related driver functions, and networking support available in the system. In this section of the reference pages, the SYNOPSIS heading of each configurable device gives a sample specification for use in constructing a system description for the config program. The DIAGNOSTICS heading lists messages that may appear on the console and in the system error log file /usr/adm/syserr/syserr.hostname due to errors in device operation.
Software support for configurable devices comes in two forms. A hardware device may be supported with a character or block device driver or, if used within the networking subsystem, may be supported with a network interface driver.
There are some devices that have fixed input/output space CSR addresses and interrupt vector addresses. There are no address switches or jumpers that need to be set up by the customer or Field Service.
Some reference pages in this section may contain suffixes to allow their files to exist with those of other reference pages having the same base name and section number. When used, suffixes are made up of one to four letters. See the man(1) reference page for more information on suffixes.
