/*
|
|
* The __cxa_atexit() function and friends are needed for full (IA64) C++ ABI
|
|
* compatibility but FreeBSD doesn't have implemented them, yet. In addition
|
|
* to the classic atexit() it is not only used to register functions to be
|
|
* called at program exit but also to call them (C++ destructors in that case)
|
|
* when a shared object is unloaded. For the later to work the dynamic linker
|
|
* assigns a unique dynamic shared object handle to every shared object while
|
|
* a handle of NULL represents a main program. When __cxa_finalize() is called
|
|
* with a specific (non-NULL) handle as an argument all functions registered
|
|
* via __cxa_atexit() and having the same handle are called.
|
|
* The best we can do here to emulate that behaviour until FreeBSD supports
|
|
* this is to register the functions via atexit(). While this certainly is a
|
|
* bad hack it seems to work, even the current dynamic linker is assigning
|
|
* the handles. I didn't see a function getting registered with an argument
|
|
* so far.
