Macro tarantool::c_ptr

macro_rules! c_ptr {
    ($s:expr) => { ... };
}

Returns a *const std::ffi::c_char constructed from the provided literal with a nul byte appended to the end. Use this to pass static c-strings when working with ffi.

Example

extern "C" {
    fn strlen(s: *const std::ffi::c_char) -> usize;
}

let count = unsafe { strlen(c_ptr!("foo bar")) };
assert_eq!(count, 7);

Same as c_str!, this macro will check at compile time if the string literal contains any interior nul bytes.
