Retrieve the supported saturation values
#include <camera/camera_api.h>
camera_error_t camera_get_supported_saturation(camera_handle_t handle, uint32_t numasked, uint32_t *numsupported, int32_t *values, bool *maxmin)
Use this function to retrieve the set of supported saturation values. You can use the values returned by this function to configure the saturation using the function camera_set_saturation().
Ensure that the values argument points to an array which has at least numasked elements allocated. To determine an appropriate size for this array, you can invoke this function in presizing mode by setting the numasked argument to 0 or the values argument to NULL. When the function is invoked in presizing mode, the maximum array size that is required is returned in the numsupported argument. You can then allocate an array of the appropriate size and invoke the function again with the numasked argument set to the value returned previously in the numsupported argument.
CAMERA_EOK when the function successfully completes, otherwise another camera_error_t value that provides the reason that the call failed.
