pub const ABS: BorrowedFd<'static>;Expand description
-EBADF—A handle that requires paths to be absolute.
This is a file descriptor which refers to no directory, which can be used
as the directory argument in *at functions such as openat, which
causes them to fail with BADF if the accompanying path is not absolute.
This corresponds to the undocumented by commonly used convention of
passing -EBADF as the dirfd argument, which is ignored if the path is
absolute, and evokes an EBADF error otherwise.
