# randalloc
randalloc is a 🚀 **BLAZING FAST**, 🚀 **MEMORY SAFE** and 🚀 **THREAD SAFE**
memory allocator. It works like this:
```c
void* malloc(size_t s) { return (void*)rand(); }
```
Actually, _a bit more_ is required to actually make `rand` work like that. Go
read [`randalloc.c`](https://github.com/portasynthinca3/randalloc/blob/master/randalloc.c),
it's just 36 lines long.
## Run it!
```
git clone https://github.com/portasynthinca3/randalloc.git
cd randalloc
cat main.c # just kinda look at what the code does
sh randalloc.sh
```
## Use it!
- Yank [`randalloc.c`](https://github.com/portasynthinca3/randalloc/blob/master/randalloc.c)
from this repo and paste it into your project.
- Call `_init_alloc` as close to entry as possible.
- Compile your project with `-Wl,--wrap=malloc -Wl,--wrap=free -Wl,--wrap=realloc`.
- Enjoy 🚀 **BLAZING FASTNESS**, 🚀 **MEMORY SAFETY** and 🚀 **THREAD
SAFETY** in your very own project that you chose to write in a legacy
language!
## Performance
The allocator runs in O(1) time. And that constant is quite small, not gonna lie.
Have I measured it? No. But it's fast; like look at it!
## Memory safety
Assuming you are fortunate enough that your allocations don't overlap, your code
will be memory safe!
## Thread safety
This allocator does not need to take any extra precautions to ensure thread
safety. That not only means it's 🚀 **BLAZING SAFE**, it's also 🚀 **THREAD
FAST**!
Wait, no, I think I might have mixed up something.
## Why?
- I just discovered the `--wrap` linker flag and my mind was absolutely
**blown**.
- I saw the original implementation in someone's Discord status.
- Yes, I am a little child.
