Hi, a question on access to C pointer in scheme:
if a C function returning a pointer is wrapped and accessed from scheme code,
int64_t * func() {
int64_t *p = make_new_pointer();
*p = // something
return p;
}
in scheme (GNU guile)
(set! p (func))
it is possible to see that p is now a pointer. How to dereference the
pointer to get the value it points to, in guile, on the scheme side?
Thanks
