Description

Object lists are used to solve issues relating to multi-threading. A sensitive list will be locked and then duplicated and a reference added to each object in the list. The sensitive list can then be unlocked and the new duplicate list can be used without fear of multi-threading issues. The list and all object references are released once the IpatchList is destroyed. NOTE: If performance sensitive code is being written IPATCH_ITEM_RLOCK, IPATCH_ITEM_WLOCK and the IpatchIter functions should probably be used instead. Directly accessing item fields can also improve performance, although less likely to be backwards compatible in future versions.

Details

IpatchList

typedef struct {
  GList *items;			/* list of GObject items */
} IpatchList;

IpatchListClass

typedef struct {
  GObjectClass parent_class;
} IpatchListClass;

ipatch_list_new ()

IpatchList* ipatch_list_new                 (void);

Create a new object list object. IpatchList objects are often used to duplicate multi-thread sensitive object lists, so they can be iterated over at one's own leasure.

Returns : New object list container object.

ipatch_list_duplicate ()

IpatchList* ipatch_list_duplicate           (IpatchList *list);

Duplicate an object list.

list : Object list to duplicate
Returns : New duplicate object list with a ref count of one which the caller owns.

ipatch_list_init_iter ()

void        ipatch_list_init_iter           (IpatchList *list,
                                             IpatchIter *iter);

Initializes a user supplied iterator (usually stack allocated) to iterate over the object list. Further operations on iter will use the list.

list : List object
iter : Iterator to initialize
