Use
The purpose of this call is to inform FileCore of the minimum period between polling for disc insertion under the given filing system.
Notes
This is so that drive lights don’t remain continuously illuminated.
The values are re-exported by FileCore in the UpCalls:
- ‘Media not present’ – see OS_UpCall 1
- ‘Media not known’ – see OS_UpCall 2
The value applies to all drives rather than a particular drive.
