Glenn, so an emulation is needed, right? What should be used if
utimensat() is not available? Is using utime() sufficient?

 Erm... do we need a |utimensat()| emulation (maybe usefull for
 abstraction purposes ?) ? Glenn ?

 ast already uses utimensat() (just within ast) if its there

 the ast usage is limited to AT_FDCWD
 its in src/lib/libast/tm/tvtouch.c
 mainly used to get ns resolution
 the #ifdef logic shows the alternatives used

OK...
... is there any |*at()| call except { |symlinkat()|, |readlinkat()|,
|utimensat()| } missing in
http://svn.nrubsig.org/svn/people/gisburn/code/openat_emu/openat_emu.c
which may be needed later ?

BTW: Where should I store the code... would src/lib/libast/fs_at/ be OK ?



Bye,
Roland
