Adding Drivers Within an Application
If you need your application to implement its own compression routines
internally, the application can add drivers to the ACM by calling the acmDriverAdd function. The application implements the driver by providing a function that
conforms to the acmDriverProc prototype. After the application has added the driver, the application can
use the driver through the ACM as it would use any other driver.
The ACM treats drivers as either global or local. An application specifies
whether a driver should be added as global or local when it calls acmDriverAdd. There are two differences between global and local drivers:
- Drivers added as global drivers are not shared with other applications.
- An application can directly alter the priority of a global driver (but not a
local driver) by calling the acmDriverPriority function. The ACM conducts a prioritized search when seeking an appropriate
driver to provide an implementation of a function call. The ACM always gives
local drivers higher priority than global drivers. The most recently added local
driver has highest priority.
