Device Files
The device files that are used by the ACC product are automatically
created as they are needed. If a daemon requires a device file that does
not exist, the daemon will create it. If an application program that makes
use of the ZCOM programmatic interface requires a device file that does
not exist, the ZCOM Interface library call that requires the device file
will create it.The following list shows the device files that are used by the
ACC product.
The major number for the following device files is dynamically allocated
upon system initialization, and can be determined using
% lsdev -d zcom0.
/dev/zmlog
This file is used by applications and utilities to send
messages to the logging mechanism zmlog.
The minor number is 0xf00000.
/dev/zmon
