-/* Resource Freeing Hooks:
-
- Normally a process exits and the OS cleans up any allocated
- memory. However, when tooling like mtrace or valgrind is monitoring
- the process we need to free all resources that are part of the
- process in order to provide the consistency required to track
- memory leaks.
-
- A single public API exists and is __libc_freeres(), and this is used
- by applications like valgrind to freee resouces.
-
- There are 3 cases:
-
- (a) __libc_freeres
-
- In this case all you need to do is define the freeing routine:
-
- foo.c:
- libfoo_freeres_fn (foo_freeres)
- {
- complex_free (mem);
- }
-
- This ensures the function is called at the right point to free
- resources.
-
- (b) __libc_freeres_ptr
-
- The framework for (a) iterates over the list of pointers-to-free
- in (b) and frees them.
-
- foo.c:
- libc_freeres_ptr (static char *foo_buffer);
-
- Freeing these resources alaways happens last and is equivalent
- to registering a function that does 'free (foo_buffer)'.
-
- (c) Explicit lists of free routines to call or objects to free.
-
- It is the intended goal to remove (a) and (b) which have some
- non-determinism based on link order, and instead use explicit
- lists of functions and frees to resolve cleanup ordering issues
- and make it easy to debug and maintain.
-
- As of today the following subsystems use (c):
-
- Per-thread cleanup:
- * malloc/thread-freeres.c
-
- libdl cleanup:
- * dlfcn/dlfreeres.c
-
- libpthread cleanup:
- * nptl/nptlfreeres.c
-
- So if you need any shutdown routines to run you should add them
- directly to the appropriate subsystem's shutdown list. */
