Macro c_string::c_str

macro_rules! c_str {
    ($lit:expr) => { ... };
}

Produce a CStr reference out of a static string literal.

This macro provides a convenient way to use string literals in expressions where a CStr reference is expected. The macro parameter does not need to end with "\0", it is appended by the macro.

Example

#[macro_use]
extern crate c_string;

extern crate libc;

fn main() {
    unsafe { libc::puts(c_str!("Hello, world!").as_ptr()) };
}
