What comes closest is scandir [1], which gives you an iterator of direntries, and can be used to avoid lstat syscalls for each file.

Otherwise you can open a dir and pass its fd to openat together with a relative path to a file, to reduce the kernel overhead of resolving absolute paths for each file.

in what way does scandir avoid stat syscalls?
