# as-malloc

This library provides a ligtweight implementation of the holy trinity of

dynamic memory allocation: `malloc`, `realloc`, `free`.

## Usage

If you have never heard of the functions above, you probably lived in a cave.

You just import the functions:

```ts

import {malloc, realloc, free} from "as-malloc";

```

Declare some unmanaged class (for easier memory access:

```ts

@unmanaged

class Foo {

	bar: i32;

	baz: f64;

}

```

Allocate the memory for that class:

```ts

const foo = changetype(malloc(offsetof()));

```

And then do whatever you want with it:

```ts

foo.bar = 35433;

foo.baz = 45.89117345;

```

## Things to remember

 - as-malloc uses only one page of WebAssembly memory (64kB). This may be

   changed on the future versions

 - If you are using any managed runtime, you should compile your program with

   `--memoryBase 65536`.
