Functions
N_JSON *	n_json_array_at (const N_JSON *arr, size_t i)
	Get an array element by index.
size_t	n_json_array_size (const N_JSON *arr)
	Number of elements in an array node.
const char *	n_json_as_string (const N_JSON *v, const char *dflt)
	Get the string value of a node itself (e.g.
int	n_json_bool (const N_JSON *obj, const char *key, int dflt)
	Get a boolean member, or a default when absent/not a boolean.
void	n_json_free (N_JSON **root)
	Free a JSON tree and NULL the caller's pointer.
N_JSON *	n_json_get (const N_JSON *obj, const char *key)
	Get a child member of an object by key (case-sensitive).
long	n_json_int (const N_JSON *obj, const char *key, long dflt)
	Get a numeric member as a long, or a default when absent/not a number.
int	n_json_is_array (const N_JSON *v)
	Report whether a node is a JSON array.
int	n_json_is_object (const N_JSON *v)
	Report whether a node is a JSON object.
N_JSON *	n_json_parse (const char *text)
	Parse a JSON document from a NUL-terminated string.
N_JSON *	n_json_parse_file (const char *path)
	Parse a JSON document from a file.
const char *	n_json_string (const N_JSON *obj, const char *key, const char *dflt)
	Get a string member, or a default when absent/not a string.
char *	n_json_string_dup (const N_JSON *obj, const char *key)
	Duplicate a string member (caller frees), or NULL when absent.
