Device Configuration Subsystem

Devices are usually pieces of equipment that attach to a computer. Devices include printers, adapters, and disk drives. Additionally, devices are special files that can handle device-related tasks.

System users cannot operate devices until device configuration occurs. To configure devices, the Device Configuration Subsystem is available.

Review the following commands and subroutines before you configure a device:

getattr subroutine
ioctl subroutine
odm_run_method subroutine
putattr subroutine
sysconfig subroutine
cfgmgr command
chdev command
mkdev command
rmdev command
SYS_CFGDD sysconfig operation
ddconfig device driver entry point
