We are using IMAQ's C API to control a Camera Link camera. Our camera's .icd file supports changing attributes such as exposure time and capture bit depth. These parameters can be adjusted inside MAX, with MAX only allowing values supported by the camera. While the C API allows for getting/setting these attribute values (ex. with the imgSet/GetCameraAttributeNumeric functions), there is no way to determine the allowed or minimum/maximum values (or even that an attribute is supported for the given camera). It would be helpful to have API functions which could access this sort of data within the .icd file.
A similar issue exists when trying to start a new imaging session: there is no way to know programmatically which cameras (if any) are connected to the machine, and if so which interface ID they are connected to ("img0", "img1"...). This data appears to already exist in the .iid files used by MAX, so it would be useful to get at that info from within C (right now, our applications just open the "img0" interface and hope everything works).
