extra	whether or not to print the returned value fields

enum explain_v4l2_crop_check_type_t explain_v4l2_crop_check_type	(	int	fildes,
		const struct v4l2_crop *	data
	)

The explain_v4l2_crop_check_type function is used to check the type member of a v4l2_crop struct.

Parameters:

fildes	The associated file descriptor
data	The crop struct to have its type member checked.
