Ted Ross created DISPATCH-1299:
----------------------------------
Summary: Provide API access to the already existing safe-reference
capability in alloc-pool
Key: DISPATCH-1299
URL: https://issues.apache.org/jira/browse/DISPATCH-1299
Project: Qpid Dispatch
Issue Type: Improvement
Components: Container
Reporter: Ted Ross
Assignee: Ted Ross
Fix For: 1.6.0
This improvement adds the following two functions to the list of functions
generated per pooled type:
{{typedef ... <typename>_sp;}}
{{void set_safe_ptr(<typename> *p, <typename>_sp *sp);}}
{{<typename> *safe_deref_<typename>(<typename>_sp sp);}}
A user of this feature can declare or allocate a safe-pointer, set the
safe-pointer using a normal object pointer, and dereference the safe-pointer
later to yield the original normal pointer. If, in the interim time, the
object was freed, the safe-dereference will yield a NULL pointer rather than a
stale (possibly re-used) pointer.
