Details
Use this function to identify the presence and range of features in the camera. The returned information identifying the features can be used to qualify calls to GetFeature and SetFeature VIs prior to use.
uFlags can be decoded using the enumerated control FEATURE_FLAGS and the VI GetFeatureFlagsHexValue.
The min and max value arrays will have multiple array elements if the requested feature has multiple parameters. See the camera system guide for details concerning the meaning of the parameters.
