QuercusVL Programming Manual

Modifies the traffic light identifier. 
In C the parameter “h” is a handler of ConfigurationDetector.  

●

RedInput

Identifier of the digital input used as a stopo signal. If using a configured traffic light, its 
value will be -1.

C++: int get_RedInput (  )
C:

int VL_ConfigurationStoppedCarDetector_get_RedInput( int h )

Returns the digital input identifier.
In C the parameter “h” is a handler of ConfigurationDetector.  

C++: void put_RedInput ( int value )
C:

void VL_ConfigurationStoppedCarDetector_put_RedInput ( int h, int n )

Modifies the digital input identifier. 
In C the parameter “h” is a handler of ConfigurationDetector.  

●

IsVideoEnabled

Shows if video generation at the units is enabled. If disabled, the unit will not generate 
videos at the detector incidences. 

C++: bool get_IsVideoEnabled (  )
C:

int VL_ConfigurationStoppedCarDetector_get_IsVideoEnabled( int h )

Returns the state of video generation.
In C the parameter “h” is a handler of ConfigurationDetector.  

C++: void put_IsVideoEnabled ( bool value )
C:

void VL_ConfigurationStoppedCarDetector_put_IsVideoEnabled ( int h, int n )

Modifies the state of video generation. 
In C the parameter “h” is a handler of ConfigurationDetector.
