Looking at rbuffer, rgc, and the lltype namespaces, it's not completely
clear to me how I would go about writing a struct with a resizable
primitive array inlined.
Something like:
typedef struct foo_t {
int a, b;
int _data[0];
}
foo_t tmp = malloc(sizeof(foo_t) + 64);
I can see that the GC has the ability to allocate "extra" memory beyond
what's required for a struct, and that lltype has the ability to inline
some lists into a struct, but how does this work in practice? And maybe I'm
missing something in the docs, so simply pointing me to some docs is also
fine.
