The FreeBSD source has some comments
dir = packed record
dd_fd : cint; // file descriptor associated with directory
dd_loc : clong; // offset in current buffer
dd_size : clong; // amount of data returned by
getdirentries
dd_buf : pchar; // data buffer
dd_len : cint; // size of data buffer
{$ifdef netbsdpowerpc}
dd_pad1 : cint;
dd_seek : cint64; // magic cookie returned by getdirentries
{$else}
dd_seek : clong; // magic cookie returned by getdirentries
{$endif}
dd_rewind : clong; // magic cookie for rewinding
dd_flags : cint; // flags for readdir
end;
TDir = dir;
pDir = ^dir;
However I would vote against using it. Sure it saves a stat here and there,
but it is way less portable (even amongst *nixes in time) than findfirst.

Keep in mind that the docs only show the Linux structures and functions for
the *nix units.
