Thanks Adam.
Is there known list of other special characters which needs to be
handled this way.
Thanks

Hey Vasanth,
Correct; I should have mentioned that use of the globbing character means that
you could match other modules. As you say, using a predicate will protect you
against erroneous matches.

That works.
Does this means the probe will match for not just "646%8859.so", but also for other module, like
"646x8859.so" or "646a8859.so" etc. Do I need to have the additional check for the specific
module in the predicate ( /probemod == "646%8859.so"/ )
Thanks

Hey Vasanth,
You might try something like this:
pid1061:646?8859.so::entry
{
...
}
You might then his a problem in the pid provider itself; let me know
and we can work from there.

Hi,
Is there a escape charater to escape the appeareance of special
characters like '%' appearing as a part of probemode or probefunc.
For example, I the following sample d-trace script which fails to compile
because of the special character '%'.This is part of the libraryname (
/usr/lib/iconv/646%8859.so )
pid1061:646%8859.so::entry
{
printf("%s|%d|%s|%s\n",execname,pid,probemod,probefunc);
}
When tried to run it fails with error "dtrace: failed to compile script
/tmp/d-scripts/runscan_1061.d: line 8: syntax error near "%"
I tried using "\" to escape "%". But that didn't help. How we handle such
cases?
Also, on an another note, how do we obtain the fullpath of the library
inside a d-script. The "probemod" by default retuurns the module name
without the path. (libxyz.so)
Thanks
Vasanth
