Function openat 

pub fn openat(
    dir_res: &impl AsResource,
    path: CString,
    flags: i32,
) -> Io<OpenAt>

Opens a file relative to a directory file descriptor.

Equivalent to the openat(2) syscall.

Examples

use std::ffi::CString;

async fn openat_example() -> std::io::Result<()> {
    let path = CString::new("/tmp/test.txt").unwrap();
    let fd = lio::api::openat(&dir, path, libc::O_RDONLY).await?;
    println!("Opened file: {:?}", fd);
    Ok(())
}
