About The Project

The project is a simple, fast, and memory-efficient pool allocator for c and c++. It is still underdevelopment and not production ready. More testing is needed to ensure it works in general cases.

Features:

• Header only
• Type-aware memory management
• Garbage collection
• Dynamic pool size

Requirements

• Compiler that supports c++ 11 or later

Getting Started

This is an example of how you may give instructions on setting up your project locally. To get a local copy up and running follow these simple example steps.

Prerequisites

A c++ compiler supporting c++ 11 or later is required.

For example:

• clang++ (linux, macos, windows, etc.)
• g++ (linux, macos, windows, etc.)
• msvc (windows)
• mingw (windows)
• cygwin-gcc (windows)

Installation

This is a header-only library. Doesn't require any other dependencies.

1. Clone the repo

   git clone https://github.com/yusing/qalloc.git
   

2. Add include as include path to your project
3. Include <qalloc/qalloc.hpp> in your project
