C programming question ....

[Ben Duncan]

Given the following snippet of code in this EXACT sequence:


struct rlib;
typedef struct rlib rlib;
struct rlib_signal_functions {
	gboolean (*signal_function)(rlib *, gpointer);
	gpointer data;
};

struct rlib_metadata {
	struct rlib_from_xml xml_formula;
	struct rlib_value rval_formula;
	struct rlib_pcode *formula_code;
};

struct rlib {
	gint current_page_number;
	gint current_line_number;
	gint detail_line_count;
	gint start_of_new_report;

         ... ... ... ... }


What is the authors intenet here with RLIB? Is declared as an
empty struct then typdef'd then ACTUALLY defined latter on?

Is this like declaring functions, except for structures?

Thanks ...
