◆ AST_LIST_APPEND_LIST

#define AST_LIST_APPEND_LIST (   head,
  list,
  field 
)

Appends a whole list to the tail of a list.

Parameters

fieldThis is the name of the field (declared using AST_LIST_ENTRY()) used to link entries of this list together.

Note: The source list (the list parameter) will be empty after calling this macro (the list entries are moved to the target list).

◆ AST_LIST_ENTRY

#define AST_LIST_ENTRY (   type)
Value:

Definition: chan_ooh323.c:109

Declare a forward link structure inside a list entry.

Parameters
typeThis is the type of each list entry.

This macro declares a structure to be used to link list entries together. It must be used inside the definition of the structure named in type, as follows:

struct list_entry {
...
AST_LIST_ENTRY(list_entry) list;
}

The field name list here is arbitrary, and can be anything you wish.

◆ AST_LIST_HEAD

#define AST_LIST_HEAD (   name,

)
Value:
struct name { \

struct type *last; \
ast_mutex_t lock; \
}
static const char type[]
Definition: chan_ooh323.c:109
struct sla_ringing_trunk * last
Definition: app_meetme.c:1092
ast_mutex_t lock
Definition: app_meetme.c:1091
struct sla_ringing_trunk * first
Definition: app_meetme.c:1092
static const char name[]
Definition: cdr_mysql.c:74

Defines a structure to be used to hold a list of specified type.

Parameters
nameThis will be the name of the defined structure.
typeThis is the type of each list entry.

This macro creates a structure definition that can be used to hold a list of the entries of type type. It does not actually declare (allocate) a structure; to do that, either follow this macro with the desired name of the instance you wish to declare, or use the specified name to declare instances elsewhere.

Example usage:

static AST_LIST_HEAD(entry_list, entry) entries;

This would define struct entry_list, and declare an instance of it named entries, all intended to hold a list of type struct entry.

◆ AST_LIST_INSERT_LIST_AFTER

#define AST_LIST_INSERT_LIST_AFTER (   head,
  list,
  elm,
  field 
)

Inserts a whole list after a specific entry in a list.

Parameters
headThis is a pointer to the list head structure
listThis is a pointer to the list to be inserted.
elmThis is a pointer to the entry after which the new list should be inserted.
fieldThis is the name of the field (declared using AST_LIST_ENTRY()) used to link entries of the lists together.

Note: The source list (the list parameter) will be empty after calling this macro (the list entries are moved to the target list).

◆ AST_LIST_INSERT_SORTALPHA

#define AST_LIST_INSERT_SORTALPHA (   head,
  elm,
  field,
  sortfield 
)

Inserts a list entry into a alphabetically sorted list.

Parameters
headPointer to the list head structure
elmPointer to the entry to be inserted
fieldName of the list entry field (declared using AST_LIST_ENTRY())
sortfieldName of the field on which the list is sorted

◆ AST_LIST_INSERT_TAIL

#define AST_LIST_INSERT_TAIL (   head,
  elm,
  field 
)

Appends a list entry to the tail of a list.

Parameters
headThis is a pointer to the list head structure
elmThis is a pointer to the entry to be appended.
fieldThis is the name of the field (declared using AST_LIST_ENTRY()) used to link entries of this list together.

Note: The link field in the appended entry is not modified, so if it is actually the head of a list itself, the entire list will be appended temporarily (until the next AST_LIST_INSERT_TAIL is performed).

◆ AST_LIST_MOVE_CURRENT

#define AST_LIST_MOVE_CURRENT (   newhead,

Value:
do { \
typeof ((newhead)->first) __extracted = __list_current; \
AST_LIST_REMOVE_CURRENT(field); \
AST_LIST_INSERT_TAIL((newhead), __extracted, field); \
} while (0)
struct sla_ringing_trunk * first
Definition: app_meetme.c:1092

Move the current list entry to another list.

Note
This is a silly macro. It should be done explicitly otherwise the field parameter must be the same for the two lists.

◆ AST_LIST_REMOVE_CURRENT

#define AST_LIST_REMOVE_CURRENT (   field)

Removes the current entry from a list during a traversal.

Parameters
fieldThis is the name of the field (declared using AST_LIST_ENTRY()) used to link entries of this list together.
Note
This macro can only be used inside an AST_LIST_TRAVERSE_SAFE_BEGIN() block; it is used to unlink the current entry from the list without affecting the list traversal (and without having to re-traverse the list to modify the previous entry, if any).

  field 
)    for((var) = (head)->first; (var); (var) = (var)->field.next)

Loops over (traverses) the entries in a list.

Parameters
headThis is a pointer to the list head structure
varThis is the name of the variable that will hold a pointer to the current list entry on each iteration. It must be declared before calling this macro.
fieldThis is the name of the field (declared using AST_LIST_ENTRY()) used to link entries of this list together.

This macro is use to loop over (traverse) the entries in a list. It uses a for loop, and supplies the enclosed code with a pointer to each list entry as it loops. It is typically used as follows:

static AST_LIST_HEAD(entry_list, list_entry) entries;
...
struct list_entry {
...
AST_LIST_ENTRY(list_entry) list;
}
...
struct list_entry *current;
...
AST_LIST_TRAVERSE(&entries, current, list) {
(do something with current here)
}
Warning
If you modify the forward-link pointer contained in the current entry while inside the loop, the behavior will be unpredictable. At a minimum, the following macros will modify the forward-link pointer, and should not be used inside AST_LIST_TRAVERSE() against the entry pointed to by the current pointer without careful consideration of their consequences:

◆ AST_LIST_TRAVERSE_SAFE_BEGIN

#define AST_LIST_TRAVERSE_SAFE_BEGIN (   head,
  var,
  field 
)

Loops safely over (traverses) the entries in a list.

Parameters
headThis is a pointer to the list head structure
varThis is the name of the variable that will hold a pointer to the current list entry on each iteration. It must be declared before calling this macro.
fieldThis is the name of the field (declared using AST_LIST_ENTRY()) used to link entries of this list together.

This macro is used to safely loop over (traverse) the entries in a list. It uses a for loop, and supplies the enclosed code with a pointer to each list entry as it loops. It is typically used as follows:

static AST_LIST_HEAD(entry_list, list_entry) entries;
...
struct list_entry {
...
AST_LIST_ENTRY(list_entry) list;
}
...
struct list_entry *current;
...
AST_LIST_TRAVERSE_SAFE_BEGIN(&entries, current, list) {
(do something with current here)
}

It differs from AST_LIST_TRAVERSE() in that the code inside the loop can modify (or even free, after calling AST_LIST_REMOVE_CURRENT()) the entry pointed to by the current pointer without affecting the loop traversal.

Defines a structure to be used to hold a read/write list of specified type.

Parameters
nameThis will be the name of the defined structure.
typeThis is the type of each list entry.

This macro creates a structure definition that can be used to hold a list of the entries of type type. It does not actually declare (allocate) a structure; to do that, either follow this macro with the desired name of the instance you wish to declare, or use the specified name to declare instances elsewhere.

Example usage:

static AST_RWLIST_HEAD(entry_list, entry) entries;

This would define struct entry_list, and declare an instance of it named entries, all intended to hold a list of type struct entry.
