/* Table entry for an attribute update handler.
|
*
|
* If the Object ID table index matches the object's ID, and the attribute table index
|
* match any of the updated attributes, then the specified handler
|
* is called. The handler is called with the object's mutex locked,
|
* and should return with mutex locked. The handler returns a bitmask of the attributes which
|
* were actually handled. This is normally the same as the attribute index,
|
* but could be a subset (including 0) if the handler discovers that the
|
* update is too complex to be handled synchronously and so must
|
* be deferred to the sync thread. Note that this direct lookup table organization
|
* gives O(1) search.
