Subject: Inhibiting heap compaction
Date: Fri, 02 Jun 2006 21:39:13 +0200 [thread overview]
Message-ID: <87y7wfxs7y.fsf@mid.deneb.enyo.de> (raw)
Is it possible to prevent the heap from being compacted, or pin
individual objects?
Suppose I write a C function C_func, which takes a string argument.
It passes that argument to some library function lib_func (which has
been written by a third party). bar invokes a C callback C_cb. In my
wrapper for Caml, C_cb invokes the Caml function cb. cb conses and
triggers heap compaction. After return from cb and C_cb, bar uses the
old address of the string, which is incorrect.
Currently, I copy all strings used in such a scenario, but this adds
quite a bit of overhead.
