Re: need to print long long with CLIB - urgent! - 1 attachment

Hi,
closing my thread self here - got info from Jeff that there's really no way
to print 64bit values with the clib print engine, sniff.

Sniff no longer, Günter, I called McGyver and he told me just to call
lltoa in LibC:

long long val = (some really big number);
char storage[20], *s;

s = lltoa( val, storage, 10 );
printf( "long long value is: %s", s );

It requires no context--and then use clib's printf to render the
returned string. I don't think clib had lltoa, so you could just add it
to your NLM's import list: I'm pretty sure it's a klib-level function.

thanks for the cool hack! Unfortunately its not that simple for me:
I have the problem with mod_jk; and the above was only one of two probs I
have: when it comes to link stage I get unresolved:
tstdiv.o -o tstdiv.nlm -commandfile tstdiv.def
### mwldnlm Linker Error:
# Undefined symbol: _rt_modu64%16 in
# tstdiv.o
### mwldnlm Linker Error:
# Undefined symbol: _rt_mul64%16 in
# tstdiv.o
### mwldnlm Linker Error:
# Undefined symbol: _rt_divu64%16 in
# tstdiv.o

and its not a useful option to just call into LibC even if its possible
because those using the CLIB build of mod_jk are most likely on older
NetWare versions (NW 5.0, 5.1 and 6.0) which probably dont have recent
LibC, and then might cause other trouble....
So I'm more on the way to decide that from now on we drop support for
NetWare CLIB builds of mod_jk for Apache 1.3.x and Netscape server;
anyway there's no Novell developer anymore hwo cares about mod_jk - so why
should I twist my mind? No user feedback at all is another reason which
makes me feel that anyway nobody uses this stuff anymore...
thanks though for your suggestion!

greetz, Guenter.

It's incredible to think that someone might actually be using NetWare
5.0. I believe, however, that this function would be on NetWare 5.1
(along with your _rt_mod... stuff which is in libc) because it's pretty
early stuff in libc.

Anyway, I'll bet Jeff would just send you the code to lltoa() if you
asked. It's pretty simple (I remember because I'm pretty sure I wrote
it) or you could get it from Free BSD. If you compiled in your clib
program, then you'd get the equivalent stuff to _rt_mod... from there no
problem.

Best regards,

Russ
