Detailed Description

These routines manage a set of registered callback data pointers. One of the easiest ways to make Squid coredump is to issue a callback to for some data structure which has previously been freed. With these routines, we register (add) callback data pointers, lock them just before registering the callback function, validate them before issuing the callback, and then free them when finished.
