8.0 version

gc-after-c-hooks

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.
