Hi Laurent,
back to your original mail:
By the way, if anyone know what lib to use for (native) to make a
lstat syscall so I can replace the stat shell call, I'd be very
grateful: I can't find where it is! (contrary to what I thought, it
is NOT in libc...)
It seems the internal symbol is '__xstat'.
From "/usr/include/x86_64-linux-gnu/sys/stat.h":
__extern_inline int
__NTH (stat (__const char *__path, struct stat *__statbuf))
{
return __xstat (_STAT_VER, __path, __statbuf);
}
That's a pity, because it makes it rather unportable.
So... If I need more speed, I'll have to make a C lib calling lstat, then call
this one with (native)... I think I'll stay with the shell call ;-)
BTW, instead of using 'line', 'split' and 'pack' in
(de stat (Path)
(mapcar pack
(split
(in
(list "stat" "-c" "%f %s %u %g %h %i %X %Y %Z" Path)
(line) )
" " ) ) )
and later parsing it with 'hex' and 'format', you could read it
directly:
(in (list "stat" "-c" "%f %s %u %g %h %i %X %Y %Z" Path)
(make
(link (hex (till " "))
(do 8
(link (read)) ) ) ) )
Thanks for this! I intended to replace the call to (multimap) when I discovered
that I had only one (hex) to call...
Regards,
