- pseudo.h (c) 1997-8 Grant R. Guenther <grant@torque.net>
- Under the terms of the GNU General Public License.
-
- This is the "pseudo-interrupt" logic for parallel port drivers.
-
- This module is #included into each driver. It makes one
- function available:
-
- ps_set_intr( void (*continuation)(void),
- int (*ready)(void),
- int timeout,
- int nice )
-
- Which will arrange for ready() to be evaluated frequently and
- when either it returns true, or timeout jiffies have passed,
- continuation() will be invoked.
-
- If nice is 1, the test will done approximately once a
- jiffy. If nice is 0, the test will also be done whenever
- the scheduler runs (by adding it to a task queue). If
- nice is greater than 1, the test will be done once every
- (nice-1) jiffies.
