enum ast_parse_flags

Support code to parse config file arguments.

The function ast_parse_arg() provides a generic interface to parse strings (e.g. numbers, network addresses and so on) in a flexible way, e.g. by doing proper error and bound checks, provide default values, and so on. The function (described later) takes a string as an argument, a set of flags to specify the result format and checks to perform, a pointer to the result, and optionally some additional arguments. It returns 0 on success, != 0 otherwise.

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 function is kind of non-intuitive in it's use. To begin, one passes NULL as the second argument. 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.

Return values:

	a	category on success
	NULL	on failure/no-more-categories

int ast_destroy_realtime	(	const char *	family,
		const char *	keyfield,
		const char *	lookup,
			...
	)

Destroy realtime configuration.

Parameters:

	family	which family/config to be destroyed
	keyfield	which field to use as the key
	lookup	which value to look for in the key field to match the entry. This function is used to destroy an entry in realtime configuration space. Additional params are used as keys.

Returns:: Number of rows affected, or -1 on error.

Note that you should use the constant SENTINEL to terminate arguments, in order to preserve cross-platform compatibility.

struct ast_variable* ast_load_realtime	(	const char *	family,
			...
	)			`[read]`

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.

The difference between these two calls is that ast_load_realtime excludes fields whose values are NULL, while ast_load_realtime_all loads all columns.

Note that you should use the constant SENTINEL to terminate arguments, in order to preserve cross-platform compatibility.

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 traditional ast_config structure rather than just returning a linked list of variables.

Note that you should use the constant SENTINEL to terminate arguments, in order to preserve cross-platform compatibility.

int ast_parse_arg	(	const char *	arg,
		enum ast_parse_flags	flags,
		void *	p_result,
			...
	)

The argument parsing routine.

Parameters:

	arg	the string to parse. It is not modified.
	flags	combination of ast_parse_flags to specify the return type and additional checks.
	result	pointer to the result. NULL is valid here, and can be used to perform only the validity checks.
	...	extra arguments are required according to flags.

Return values:

	0	in case of success, != 0 otherwise.
	result	returns the parsed value in case of success, the default value in case of error, or it is left unchanged in case of error and no default specified. Note that in certain cases (e.g. sockaddr_in, with multi-field return values) some of the fields in result may be changed even if an error occurs.

Examples of use: ast_parse_arg("223", PARSE_INT32|PARSE_IN_RANGE, &a, -1000, 1000); returns 0, a = 223 ast_parse_arg("22345", PARSE_INT32|PARSE_IN_RANGE|PARSE_DEFAULT, &a, 9999, 10, 100); returns 1, a = 9999 ast_parse_arg("22345ssf", PARSE_UINT32|PARSE_IN_RANGE, &b, 10, 100); returns 1, b unchanged ast_parse_arg("www.foo.biz:44", PARSE_INADDR, &sa); returns 0, sa contains address and port ast_parse_arg("www.foo.biz", PARSE_INADDR|PARSE_PORT_REQUIRE, &sa); returns 1 because port is missing, sa contains address

int ast_realtime_require_field	(	const char *	family,
			...
	)

Inform realtime what fields that may be stored.

Parameters:

family

which family/config is referenced This will inform builtin configuration backends that particular fields may be updated during the use of that configuration section. This is mainly to be used during startup routines, to ensure that various fields exist in the backend. The backends may take various actions, such as creating new fields in the data store or warning the administrator that new fields may need to be created, in order to ensure proper function.

The arguments are specified in groups of 3: column name, column type, and column size. The column types are specified as integer constants, defined by the enum require_type. Note that the size is specified as the number of equivalent character fields that a field may take up, even if a field is otherwise specified as an integer type. This is due to the fact that some fields have historically been specified as character types, even if they contained integer values.

A family should always specify its fields to the minimum necessary requirements to fulfill all possible values (within reason; for example, a timeout value may reasonably be specified as an INTEGER2, with size 5. Even though values above 32767 seconds are possible, they are unlikely to be useful, and we should not complain about that size).

Return values:

	0	Required fields met specified standards
	-1	One or more fields was missing or insufficient

Note that you should use the constant SENTINEL to terminate arguments, in order to preserve cross-platform compatibility.

int ast_store_realtime	(	const char *	family,
			...
	)

Create realtime configuration.

Parameters:

family

which family/config to be created This function is used to create a parameter in realtime configuration space.

Returns:: Number of rows affected, or -1 on error. On the MySQL engine only, for reasons of backwards compatibility, the return value is the insert ID. This value is nonportable and may be changed in a future version to match the other engines.

Note that you should use the constant SENTINEL to terminate arguments, in order to preserve cross-platform compatibility.

int ast_unload_realtime ( const char * family )

Release any resources cached for a realtime family.

Parameters:

family

which family/config to destroy Various backends may cache attributes about a realtime data storage facility; on reload, a front end resource may request to purge that cache.

int ast_update2_realtime	(	const char *	family,

Update realtime configuration.

Parameters:

family

which family/config to be updated This function is used to update a parameter in realtime configuration space. It includes the ability to lookup a row based upon multiple key criteria. As a result, this function includes two sentinel values, one to terminate lookup values and the other to terminate the listing of fields to update.

Returns:: Number of rows affected, or -1 on error.
