dtrace discuss - Mar 2009 - integrating dtrace with other scripting language

hi

i was told that dtrace program can not accesses the information
present in the core dump file but we can pass  the information present
in the file to dtrace program using some scripting language.

can anybody suggest me where i can get information on how to integrate
dtrace with scripting language to access files''s information ?

Can you be more specific?

The DTraceToolKit is loaded with examples
of integrating DTrace with Perl and Shell,
but I''m not sure if this is what you mean.

Get the DTraceToolKit here;

dtracing is for a running system.

This is unclear.

There are 2 different things:
1. Calling dtrace utility from within other scripts. DTraceToolkit
(http://www.opensolaris.org/os/community/dtrace/dtracetoolkit) has
ample examples
2. Being able to use dtrace APIs from within a scripting language
seamlessly (for ex like a function call in perl/tcl/python/etc). For
this one needs to write language bindings for the scripting language
based on APIs provided by libdtrace. This is more involved work. You
may look at http://dev.lrem.net/tcldtrace as an example (for tcl)
