Retrieve the supported sharpness values
#include <camera/camera_api.h>
camera_error_t camera_get_supported_sharpness(camera_handle_t handle, uint32_t numasked, uint32_t *numsupported, int32_t *values, bool *maxmin)
Use this function to retrieve the set of supported sharpness values. You can use the values returned by this function to configure the sharpness using the function camera_set_sharpness().
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.
