getAppleSense

Return display sense information for legacy Apple sensing.

Declaration

virtual IOReturn getAppleSense(
 IOIndexconnectIndex, 
 UInt32 *senseType, 
 UInt32 *primary, 
 UInt32 *extended, 
 UInt32 *displayType );

Parameters

  • connectIndex:

    Index of the display connection, from zero to the value of getConnectionCount().

  • senseType:

    Return zero to indicate legacy Apple sensing.

  • primary:

    Return the value of the primary Apple sense code.

  • extended:

    Return the value of the secondary Apple sense code.

  • displayType:

    Return an Apple defined constant for the type of display sensed. For example, kVGAConnect, kNTSCConnect, kPALConnect etc.

Return Value

An IOReturn code.

Overview

Hardware that supports simple display sensing, or the classic 3 pin Apple sensing described in Designing Cards and Drivers, should implement this method to return sense information.
