PURPOSE:
|
||
|
|
(This header file defines the "RELEASE()" macro for supported platforms.
|
||
|
|
The release function should yield the processor from the processes that
|
||
|
|
makes the call. This allows the UNIX schedular to arbitrate process
|
||
|
|
priorities during spinloops based on the status of processes waiting
|
||
|
|
to run)
