Arguments:
Returns a list whose entries each represent a C (or C-compatible) function to call after garbage collections of any kind. The typical declaration of the C function can be
int myafterhook(void);
The list entry itself must be an (unsigned-byte 32) array of at least 1 entry, and its first entry must be the address of the C function.
setf can be used to store into the list.
A typical usage of this feature is
(let ((myaddr (ff:get-entry-point "myafterhook")))
(push (make-array 1 :element-type '(unsigned-byte 32)
:initial-element myaddr)
(excl:gc-after-c-hooks)))
No gc hooks are saved across dumplisps. All applications are responsible for re-establishing their own gc-after-c-hooks.
See also gc.htm for general information on garbage collection in Allegro CL.
