char* ast_category_browse	(	struct ast_config *	config,
		const char *	prev
	)

Goes through categories.

Parameters:

	config	Which config structure you wish to "browse"
	prev	A pointer to a previous category. This funtion is kind of non-intuitive in it's use. To begin, one passes NULL as the second arguement. It will return a pointer to the string of the first category in the file. From here on after, one must then pass the previous usage's return value as the second pointer, and it will return a pointer to the category name afterwards.

Returns a category on success, or NULL on failure/no-more-categories

struct ast_variable* ast_load_realtime	(	const char *	family,
			...
	)

Retrieve realtime configuration.

Parameters:

family

which family/config to lookup This will use builtin configuration backends to look up a particular entity in realtime and return a variable list of its parameters. Note that unlike the variables in ast_config, the resulting list of variables MUST be freed with ast_variables_destroy() as there is no container.

struct ast_config* ast_load_realtime_multientry	(	const char *	family,
			...
	)

Retrieve realtime configuration.

Parameters:

family

which family/config to lookup This will use builtin configuration backends to look up a particular entity in realtime and return a variable list of its parameters. Unlike the ast_load_realtime, this function can return more than one entry and is thus stored inside a taditional ast_config structure rather than just returning a linked list of variables.
