This function accesses the configuration of a device or software module using the GenICam GenApi interface. The actual GenApi interface is accessed through the handle of opened device or software module provided by other subsystem (like opened GigEVision device handle). A call to this function may result in time expensive (blocking) data exchange with device.

Return value

False, when GenApi description does not provide a parameter or command with specified name. True, when any kind of parameter or command exists in the referenced GenApi description, regardless of its interface, implementation state or availability (use GenApi_GetParamDescriptor function to retrieve more information about existing parameter).


This function will throw an exception in the following situations:

  • Object handle is invalid or does not provide the GenApi interface.
