dlibc - Dynamic Libc Bindings for Rust

中文 • English

Dynamically generated glibc/musl/... bindings created at compile time using your system's actual header files.

The current libc crate in the Rust ecosystem has some issues:

• Unable to quickly follow system changes (insufficient manpower)
• Cannot handle conflicting symbols between different versions (e.g., time_t/time64)
• Cannot support xxx_MAX symbols (libc intentionally prevents adding such symbols to avoid incompatibility)

This crate can serve as a supplement to libc, capable of using the actual header files from your current system. However, compared to libc, there are some requirements:

• The system needs to support bindgen and its dependencies like clang-dev
• If you need to interact with the kernel, you also need to install kernel header files, such as: linux-libc-dev

Features

• 🚀 All bindings generated at compile time using bindgen
• 📁 File path structure mapped to Rust module hierarchy, providing consistent experience with C programs

Usage

Add to your Cargo.toml:

[dependencies]
dlibc = "0.1"

Usage:

use dlibc::stdio;

fn main() {
    unsafe {
        // Call system functions directly
        stdio::printf(c"Hello, dynamic libc!\n".as_ptr());
    }
}

TODO

• BSD support
• Support for function macros
• Support for detecting symbol existence in dependent packages, i.e., ifdef

Note

Some feature PRs that the current bindgen dependency relies on have not been merged yet and haven't been published to crates.io. If needed, please use the GitHub repository directly.
