Browse categories.

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.

int ast_realtime_require_field | ( | const char * | family, |

) |
Inform realtime what fields that may be stored.
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).
0 | Required fields met specified standards |
-1 | One or more fields was missing or insufficient |
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.

int ast_variable_lists_match | ( | const struct ast_variable * | left, |

Tests 2 variable lists to see if they match.
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.
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.

int ast_variables_match | ( | const struct ast_variable * | left, |
const struct ast_variable * | right | ||
) |
Tests 2 variable values to see if they match.
left | Variable to test |
right | Variable to match against with an optional realtime-style operator in the name |
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.
