ast_parse_flags

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.

Returns

0 on success, != 0 otherwise.

ast_category_browse()

static char * ast_category_browse	(	struct ast_config *	config,
		const char *	prev_name
	)

Browse categories.

Parameters

config	Which config structure you wish to "browse"
prev_name	A pointer to a previous category name.

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 name on success
NULL	on failure/no-more-categories

Note

ast_category_browse maintains internal state. Therefore is not thread safe, cannot be called recursively, and it is not safe to add or remove categories while browsing. ast_category_browse_filtered does not have these restrictions.

ast_destroy_realtime()

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

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

ast_load_realtime_fields()

struct ast_variable * ast_load_realtime_fields	(	const char *	family,
		const struct ast_variable *	fields
	)

Retrieve realtime configuration.

Parameters

family	which family/config to lookup
fields	which fields 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

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.

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

ast_load_realtime_multientry()

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

Returns

An ast_config with one or more results

Return values

NULL	Error or no results returned

Note

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

ast_parse_arg()

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.
p_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("12", PARSE_UINT32|PARSE_IN_RANGE|PARSE_RANGE_DEFAULTS, &a, 1, 10); returns 1, a = 10 ast_parse_arg("223", PARSE_TIMELEN|PARSE_IN_RANGE, &a, TIMELEN_SECONDS, -1000, 1000); returns 0, a = 1000 ast_parse_arg("223", PARSE_TIMELEN|PARSE_IN_RANGE, &a, TIMELEN_SECONDS, -1000, 250000); returns 0, a = 223000 ast_parse_arg("223", PARSE_TIMELEN|PARSE_IN_RANGE|PARSE_DEFAULT, &a, TIMELEN_SECONDS, 9999, -1000, 250000); returns 0, a = 9999 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

ast_realtime_require_field()

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

Inform realtime what fields that may be stored.

Since

1.6.1

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

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

TODO The return value of this function is routinely ignored. Ignoring the return value means that it's mostly pointless to be calling this. You'll see some warning messages potentially, but that's it.

XXX This function is super useful for detecting configuration problems early, but unfortunately, the latest in configuration management, sorcery, doesn't work well with this. Users of sorcery are familiar with the fields they will need to write but don't know if realtime is being used. Sorcery knows what storage mechanism is being used but has no high-level knowledge of what sort of data is going to be written.

ast_update2_realtime()

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.

Note

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

Appends a variable list to the end of another list.

Parameters

head	A pointer to an ast_variable * of the existing variable list head. May NOT be NULL but the content may be to initialize a new list. If so, upon return, this parameter will be updated with a pointer to the new list head.
search_hint	The place in the current list to start searching for the end of the list. Might help performance on longer lists. If NULL, it defaults to head.
new_var	The head of the new variable list to be appended

Returns

The tail of the resulting list.

Note

If the existing *head is NULL, it will be updated to new_var. This allows you to call ast_variable_list_append in a loop or callback without initializing the list first.

ast_variable_list_replace()

int ast_variable_list_replace	(	struct ast_variable **	head,
		struct ast_variable *	replacement
	)

Replace a variable in the given list with a new value.

Since

13.30.0

Parameters

head	A pointer to an ast_variable * of the existing variable list head. May NOT be NULL but the content may be to initialize a new list. If so, upon return, this parameter will be updated with a pointer to the new list head.
replacement	The variable that replaces another variable in the list with the same name.

Return values

0	if a variable was replaced in the list
-1	if no replacement occured

Note

The variable name comparison is performed case-sensitively

If a variable is replaced, its memory is freed.

ast_variable_list_replace_variable()

int ast_variable_list_replace_variable	(	struct ast_variable **	head,
		struct ast_variable *	oldvar,
		struct ast_variable *	newvar
	)

Replace a variable in the given list with a new variable.

Parameters

head	A pointer to the current variable list head. Since the variable to be replaced, this pointer may be updated with the new head.
oldvar	A pointer to the existing variable to be replaced.
newvar	A pointer to the new variable that will replace the old one.

Return values

0	if a variable was replaced in the list
-1	if no replacement occured

Note

The search for the old variable is done simply on the pointer.

If a variable is replaced, its memory is freed.

ast_variable_lists_match()

int ast_variable_lists_match	(	const struct ast_variable *	left,
		const struct ast_variable *	right,
		int	exact_match
	)

Tests 2 variable lists to see if they match.

Since

13.9.0

Parameters

left	Variable list to test
right	Variable list with an optional realtime-style operator in the names
exact_match	If true, all variables in left must match all variables in right and vice versa. This does exact value matches only. Operators aren't supported. Except for order, the left and right lists must be equal.

If false, every variable in the right list must match some variable in the left list using the operators supplied. Variables in the left list that aren't in the right list are ignored for matching purposes.

Return values

1	matches
0	doesn't match

Iterates over the variable lists calling ast_variables_match. If any match fails or a variable in the right list isn't in the left list, 0 is returned.

ast_variables_match()

int ast_variables_match	(	const struct ast_variable *	left,
		const struct ast_variable *	right
	)

Tests 2 variable values to see if they match.

Since

13.9.0

Parameters

left	Variable to test
right	Variable to match against with an optional realtime-style operator in the name

Return values

1	matches
0	doesn't match

The values of the variables are passed to ast_strings_match. If right->name is suffixed with a space and an operator, that operator is also passed to ast_strings_match.

Examples:

left->name = "id" (ignored) left->value = "abc" right->name = "id regex" (id is ignored) right->value = "a[bdef]c"

will result in ast_strings_match("abc", "regex", "a[bdef]c") which will return 1.

left->name = "id" (ignored) left->value = "abc" right->name = "id" (ignored) right->value = "abc"

will result in ast_strings_match("abc", NULL, "abc") which will return 1.

See the documentation for ast_strings_match for the valid operators.
