Adds a depender into the list of objects which should not be destroyed before
this iobject. It’s usually used for cases where the iobject uses native libical
structure from the depender. The depender is referenced. It’s illegal to try
to add one depender multiple times.
Obtain the ICalObject::always-destroy property value.
Obtains whether the native libical structure is a global shared memory,
thus should not be destroyed. This can be set only during construction time.
Obtain native libical structure pointer associated with this iobject.
Obtain a pointer to a function responsible to free the libical native structure.
Obtain current owner of the native libical structure. The returned pointer,
if not NULL, is referenced for thread safety. Unref it with g_object_unref
when done with it.
Removes a depender from the list of objects which should not be destroyed before
this iobject, previously added with i_cal_object_add_depender(). It’s illegal to try
to remove the depender which is not in the internal list.
Unref and remove the owner.
Sets the ICalObject::always-destroy property value. When TRUE, the native
libical structure is always freed, even when an owner of the iobject is set.
Sets a function to be used to destroy the native libical structure.
Sets an owner of the native libical structure, that is an object responsible
for a destroy of the native libical structure.
Obtain native libical structure pointer associated with this iobject and sets the one
at iobject to NULL, thus it’s invalid since now on.
