Define Documentation

#define AST_LIST_APPEND_LIST ( head,
list,
field   ) 

Appends a whole list to the tail of a list.

Parameters:
head This is a pointer to the list head structure
list This is a pointer to the list to be appended.
field This is the name of the field (declared using AST_LIST_ENTRY()) used to link entries of the 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).

Definition at line 723 of file linkedlists.h.

Referenced by __ast_queue_frame(), announce_thread(), ast_do_masquerade(), clone_variables(), and process_weights().

#define AST_LIST_EMPTY ( head   )     (AST_LIST_FIRST(head) == NULL)

#define AST_LIST_ENTRY ( type   ) 

Value:

struct {                      \
   struct type *next;                  \
}
Declare a forward link structure inside a list entry.

Parameters:
type This 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.

Definition at line 374 of file linkedlists.h.

#define AST_LIST_FIRST ( head   )     ((head)->first)

#define AST_LIST_HEAD ( name,
type   ) 

Value:

struct name {                       \
   struct type *first;                 \
   struct type *last;                  \
   ast_mutex_t lock;                \
}
Defines a structure to be used to hold a list of specified type.

Parameters:
name This will be the name of the defined structure.
type This 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_mutex_destroy(&(head)->lock);            \
}
Destroys a list head structure.

Parameters:
head This is a pointer to the list head structure
This macro destroys a list head structure by setting the head entry to NULL (empty list) and destroying the embedded lock. It does not free the structure from memory.

#define AST_LIST_TRAVERSE ( head,
var,
field   )     for((var) = (head)->first; (var); (var) = (var)->field.next)

Loops over (traverses) the entries in a list.

Parameters:
head This is a pointer to the list head structure
var This 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.
field This 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:

#define AST_LIST_TRAVERSE_SAFE_BEGIN ( head,
var,
field   ) 

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

Parameters:
head This is a pointer to the list head structure
var This 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.
field This 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)
  }
  AST_LIST_TRAVERSE_SAFE_END;

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.

struct name {                                                           \
        struct type *first;                                             \
        struct type *last;                                              \
        ast_rwlock_t lock;                                              \
}
Defines a structure to be used to hold a read/write list of specified type.

Parameters:
name This will be the name of the defined structure.
type This 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.

#define AST_RWLIST_HEAD_DESTROY ( head   ) 

Value:

{                                 \
        (head)->first = NULL;                                           \

        ast_rwlock_destroy(&(head)->lock);                              \
}
Destroys an rwlist head structure.

Parameters:
head This is a pointer to the list head structure
This macro destroys a list head structure by setting the head entry to NULL (empty list) and destroying the embedded lock. It does not free the structure from memory.

#define AST_RWLIST_HEAD_SET ( head,
entry   ) 

Value:

do {                           \
        (head)->first = (entry);                                        \
        (head)->last = (entry);                                         \
        ast_rwlock_init(&(head)->lock);                                 \
} while (0)
Initializes an rwlist head structure with a specified first entry.

Parameters:
head This is a pointer to the list head structure
entry pointer to the list entry that will become the head of the list
This macro initializes a list head structure by setting the head entry to the supplied value and recreating the embedded lock.

#define AST_RWLIST_HEAD_STATIC ( name,
type   ) 

Value:

struct name {                                                           \
        struct type *first;                                             \
        struct type *last;                                              \
        ast_rwlock_t lock;                                              \
} name = AST_RWLIST_HEAD_INIT_VALUE
Defines a structure to be used to hold a read/write list of specified type, statically initialized.

Parameters:
name This will be the name of the defined structure.
type This 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, and allocates an instance of it, initialized to be empty.

Example usage:

This would define struct entry_list, intended to hold a list of type struct entry.
