# [−][src]Function nix::sys::stat::fchmodat

    pub fn fchmodat<P: ?Sized + NixPath>(
        dirfd: Option<RawFd>,
        path: &P,
        mode: Mode,
        flag: FchmodatFlags
    ) -> Result<()>

Change the file permission bits.

The file to be changed is determined relative to the directory associated with the file descriptor `dirfd` or the current working directory if `dirfd` is `None`.

If `flag` is `FchmodatFlags::NoFollowSymlink` and `path` names a symbolic link, then the mode of the symbolic link is changed.

`fchmod(None, path, mode, FchmodatFlags::FollowSymlink)` is identical to a call `libc::chmod(path, mode)`. That's why `chmod` is unimplemented in the `nix` crate.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
