buddy_alloc
A single-header buddy memory allocator for C and C++ with bounded performance and predictable metadata overhead.
What is buddy_alloc?
buddy_alloc is a single-header buddy memory allocator for C and C++ that provides predictable allocation and deallocation behavior with bounded performance and fixed metadata overhead. It is designed for use in systems where traditional allocators may not meet strict timing or storage requirements, such as embedded environments, game consoles, or kernels.
Developers working on embedded systems, game engines, operating system kernels, or any C/C++ project requiring deterministic memory allocation with minimal fragmentation and reliable performance bounds.
It offers guaranteed bounded allocation/deallocation costs and predictable metadata size, unlike general-purpose allocators, making it ideal for real-time and resource-constrained applications. Its single-header design and portability across compilers and platforms simplify integration.
