How do I avoid using slices?

[mrjbom (German)]

Hello.
I needed to use double-linked lists in my app, there is a GList for this, but I can’t use the entire glib.

I am trying to isolate only the glist code(glist.h glist.c) to use only two-linked lists.

However, I have encountered the glist code using gslice to work with memory, I would like to avoid this. Can I replace the slice mechanism with regular calls to malloc() and free()? How is this easier to do?

Again, I need to use glist.c and glist.h separate from other code, I only need to replace the use of slices with normal functions.

Thanks.

You can’t. GLib is not a copy-paste library, or a piecemeal one. You can only depend on the whole GLib, or nothing.

The GList implementation is not really hard to replicate outside of GLib. GList has some additional niceties, like using a slab allocator that makes freeing lists a near-constant time operation; but, of course, that comes at the cost of using GLib.

To be fair, if you’re using plain C, I’d strongly recommend depending on GLib; the linker will only ever page in the necessary symbols, and the shared library itself is fairly small, once stripped.

Using GList without dependencies?

Hi. In my program, I need to use two-linked lists. I would like to use GList, but you can’t pull the entire library for just one thing. I am interested in the glist.h and glist.c files, can I only use them and not drag other GLib files with me? How to do this? Thanks.

If I replace the slices with normal memory management functions in the glists code, I can use glists without the rest of the library, I’m just wondering how to do it.

Well nobody is stopping you using plain malloc/free, but really at that point you may as well roll your own linked list or use existing kernel-friendly linked lists

…as suggested in the original topic

If I replace g_slice_new(GList) with malloc(sizeof(GList)) and similarly with other functions, will everything work as it should?
