dtrace discuss - Oct 2008 - need help

I am trying to find uid from getpwuid_r function; here is what I tried so far

dtrace -n ''pid5734:libc.so.1:getpwuid_r:entry {trace(arg0)}'' 

the result is a big number that doesn''t match any uid''s; am I
doing anything wrong? the process in question is svc.startd. Is there a way to
know if there is a legitimate value in the arguments?

also is there is any difference in using libc vs libc.so.1 in the cmd above?

Thanks

Depending on the ISA that you''re on, you may have extraneous garbage  
in the
high bits. Try casting arg0 to an int: trace((int)arg0);
