C-Low level library

Personal use low level, since it's C, primarly an allocator library (for now). The aim of the project is to collect many independant and portable C utilities where third-parties are not well suited or do not have a good API, to be used in realtime/fast and clean APIs for game dev.

Plans in the future to add more utilities custom stuff.

Written in ANSI C, compliant to all C version up to C17 (at least what I've tested), but also compiles for C++.

Features

• freelist Basically a non fixed size slab allocator with internal linked list tracking of free memory.
• gpalloc General purpose allocator with external linked list tracking of free memory with alignment in mind.
• slice Index based slice allocator with binary search and coalescence tracking of free slices.

Usage

Clone/download the repo add include to your project or just copy the needed files.

See tests.

Contribution

If you want to submit you own utility, one rule is to have not depend on external, non standard stuff. Compile in C but also C++, be as portable/crossplatform as possible. And make automatic tests for it.
