27/* Resource Freeing Hooks:
28
29 Normally a process exits and the OS cleans up any allocated
30 memory. However, when tooling like mtrace or valgrind is monitoring
31 the process we need to free all resources that are part of the
32 process in order to provide the consistency required to track
33 memory leaks.
34
35 A single public API exists and is __libc_freeres, and this is used
36 by applications like valgrind to free resources.
37
38 Each free routines must be explicit listed below. */
