Hi, I've been looking through the cupcake sensor framework code. It's puzzling me that certain parts of the code look like they are designed to support multiple devices, in the sense of having multiple control and/or data device file descriptors open, but other parts of the code give no means of accessing things this way.
In sensors.h, function pointers open_data_source and so on are set to take a pointer to struct sensors_control_device_t. The original module open passes in a handle to that pointer type, so obviously one could set up an array of devices. But it only appears possible to get back one file descriptor to pass on to open_data. Further, it would be nice to then pass a particular device when, say, changing the sensor event delay. But in all the SensorService and SensorManager code, I see no way to use any parameter besides the base sSensorDevice pointers (which aren't globally accessible). So, if I have two devices I need to open (say, /dev/foo and /dev/bar), am I just supposed to track file descriptors for them internally? What's the point of passing back a fd at all then? Seems so close to being nice and general, but not quite. Am I missing the point somewhere?
