Functions

int ast_db_del (const char *family, const char *keys)
 Delete entry in astdb.
int ast_db_deltree (const char *family, const char *keytree)
 Delete one or more entries in astdb If both parameters are NULL, the entire database will be purged. If only keytree is NULL, all entries within the family will be purged. It is an error for keytree to have a value when family is NULL.
void ast_db_freetree (struct ast_db_entry *dbe)
 Free structure created by ast_db_gettree()
int ast_db_get (const char *family, const char *keys, char *value, int valuelen)
 Get key value specified by family/key.
struct ast_db_entryast_db_gettree (const char *family, const char *keytree)
 Get a list of values within the astdb tree If family is specified, only those keys will be returned. If keytree is specified, subkeys are expected to exist (separated from the key with a slash). If subkeys do not exist and keytree is specified, the tree will consist of either a single entry or NULL will be returned.
int ast_db_put (const char *family, const char *keys, const char *value)
 Store value addressed by family/key.
