swift-dlmalloc

This is a SwiftPM package for dlmalloc which is a general-purpose memory allocator written by Doug Lea. Typically, this package is helpful when you need a memory allocator implementation for Embedded Swift applications.

Supported Platforms

Target triplet Supported
wasm32-unknown-none-wasm ✅

Feel free to create a PR to add support for other platforms.

Usage

Add the following dependency to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/swiftwasm/swift-dlmalloc", from: "0.1.0"),
]

Then, add dlmalloc as a dependency for your target:

.executableTarget(
    name: "Examples",
    dependencies: [
        .product(name: "dlmalloc", package: "swift-dlmalloc"),
    ]
)

Finally, import dlmalloc module in your Swift code:

import dlmalloc

public func main() {
    let ptr = dlmalloc.malloc(8)!
    ptr.storeBytes(of: 42, as: Int.self)
    print("malloc(8) = \(ptr)\n")
    print("*(\(ptr)) = \(ptr.load(as: Int.self))\n")

    dlmalloc.free(ptr)
}
