OS_ScreenMode 67

(SWI &65)
Entry
R0 67
R1 Driver number
Exit
All registers preserved

Use

GraphicsV drivers should make this call in order to release a driver ID that was previously allocated by OS_ScreenMode 64.

Notes

An error will be returned if the driver ID is invalid or the driver is still in the ‘started’ state (i.e. OS_ScreenMode 66 has not been called).

Before making this call the driver must make sure it has released its claim on GraphicsV and has stopped generating VSync calls.
