Function nc::access

pub unsafe fn access<P: AsRef<Path>>(
    filename: P,
    mode: i32
) -> Result<(), Errno>

It uses the real user ID and the group access list to authorize the request.

Example

let ret = unsafe { nc::access("/etc/passwd", nc::F_OK) };
assert!(ret.is_ok());
let ret = unsafe { nc::access("/etc/passwd", nc::X_OK) };
assert!(ret.is_err());
