Query state:

ProcRRGetScreenInfo/ProcRRGetScreenResources
|

RRGetInfo
|
|
|
|
• Request configuration from driver, either 1.0 or 1.2 style
|
|
• These functions only record state changes, all
|
|
other actions are pended until RRTellChanged is called
|

|
|
|

• Must delay scanning configuration until after ->rrGetInfo returns
|

because some drivers will call SetCurrentConfig in the middle
|
|
of the ->rrGetInfo operation.
|
|

Asynchronous state setting (1.2 only)
|
|
When setting state asynchronously, the driver invokes the

->rrGetInfo function and then calls RRTellChanged to flush

the changes to the clients and reset pointer if necessary
