pub fn fstatvfs<Fd: AsFd>(fd: Fd) -> Result<StatVfs>Available on crate feature
fs only.Expand description
fstatvfs(fd)—Queries filesystem statistics for an open file or
directory, POSIX version.
Compared to fstatfs, this function often provides less information,
but it is more portable. But even so, filesystems are very diverse and not
all the fields are meaningful for every filesystem. And f_fsid doesn’t
seem to have a clear meaning anywhere.
