I also had this problem (when I created a readdir equivalent for a port of a
non-libc using compiler).
I checked libc, and libc always seems to use 1024 bytes (constant called DIRBLKSIZ)
for nbytes. But I didn't try to
search /proc yet.
Also keep in mind that using getdirentries you could get duplicate entries
(libc readdir sorts and removes duplicates first).
I however don't know if this is just because of hardlinks (which most people
don't use afaik) or also for regular filehandling.
