flagsOBJ_NOLOCK to avoid locking weakproxy.

Note
obj must be newly created, this procedure is not thread safe if any other code can reach obj before this procedure ends.
weakproxy may be previously existing, but must not currently have an object set.
The only way to unset an object is for it to be destroyed. Any call to this function while an object is already set will fail.

◆ ao2_object_get_lockaddr()

void* ao2_object_get_lockaddr ( void *  obj)

Return the mutex lock address of an object.

Parameters
[in]objA pointer to the object we want.
Returns
the address of the mutex lock, else NULL.

This function comes in handy mainly for debugging locking situations, where the locking trace code reports the lock address, this allows you to correlate against object address, to match objects to reported locks.

Warning
AO2 lock objects do not include tracking fields when DEBUG_THREADS is not enabled.
Since
1.6.1

◆ ao2_weakproxy_subscribe()

int ao2_weakproxy_subscribe ( void *  weakproxy,
ao2_weakproxy_notification_cb  cb,
void *  data,
int  flags 
)

Request notification when weakproxy points to NULL.

Since
14.0.0
Parameters
weakproxyThe weak object
cbProcedure to call when no real object is associated
dataPassed to cb
flagsOBJ_NOLOCK to avoid locking weakproxy.
Return values
0Success
-1Failure
Note
Callbacks are run in the reverse order of subscriptions.
This procedure will allow the same cb / data pair to be added to the same weakproxy multiple times.
It is the caller's responsibility to ensure that *data is valid until after cb() is run or ao2_weakproxy_unsubscribe is called.
If the weakproxy currently points to NULL the callback will be run immediately, without being added to the subscriber list.

◆ ao2_weakproxy_unsubscribe()

int ao2_weakproxy_unsubscribe ( void *  weakproxy,
ao2_weakproxy_notification_cb  cb,
void *  data,
int  flags 
)

Remove notification of real object destruction.

Since
14.0.0
Parameters
weakproxyThe weak object
cbCallback to remove from destroy notification list
dataData pointer to match
flagsOBJ_NOLOCK to avoid locking weakproxy. OBJ_MULTIPLE to remove all copies of the same cb / data pair.
Returns
The number of subscriptions removed.
Return values
0cb / data pair not found, nothing removed.
-1Failure due to invalid parameters.
Note
Unless flags includes OBJ_MULTIPLE, this will only remove a single copy of the cb / data pair. If it was subscribed multiple times it must be unsubscribed as many times. The OBJ_MULTIPLE flag can be used to remove matching subscriptions.
When it's time to run callbacks they are copied to a temporary list so the weakproxy can be unlocked before running. That means it's possible for this function to find nothing before the callback is run in another thread.
