1st No one has wanted it yet

2nd It's a little trickier to implement in a generic way because in c
you don't know the bounds of the array.

3rd It's easy to implement a input custom provider.

You need to implement these methods: (rlib_input.h)

typedef struct input_filter input_filter;
struct input_filter {
	gpointer private;
	struct input_info info;
	gint (*input_close)(gpointer);
	gpointer (*new_result_from_query)(gpointer, gchar *);
	gint (*free)(gpointer);
	gint (*first)(gpointer, gpointer);
	gint (*next)(gpointer, gpointer);
	gint (*previous)(gpointer, gpointer);
	gint (*last)(gpointer, gpointer);
	gint (*isdone)(gpointer, gpointer);
	const gchar * (*get_error)(gpointer);
	gchar * (*get_field_value_as_string)(gpointer, gpointer, gpointer);
	gpointer (*resolve_field_pointer)(gpointer, gpointer, gchar *);
	void (*free_result)(gpointer, gpointer);	
	gint (*set_encoding)(gpointer);
};

See MySQL, ODBC, PostgreeSQL as example. Other people have posted to the
list input providers (someone did a XML but didn't sign the
copyright :( )

Then you call
rlib_add_datasource(r, "SOME_NAME", input);

And away you go.
