} DDC_errCode
Prototype In
snap/ddc.h
Description
Returns values from DDC_initExt and MCS_initExt functions.
The ddcOk value indicates that the DDC communications channel was initialised successfully for both the graphics card and the monitor.
The ddcNotAvailable value indicates that the graphics card does not support DDC communications or that this feature is disabled for the device driver.
The ddcNoCommunication value indicates that the graphics card does support DDC communications, however the monitor is not responding on the DDC communications channel. The most likely cause of this is that the monitor attached to the graphics card is not DDC2B enabled.
