Look at the ‘psin’ command and ‘pidin me’.

You might find “spin” (included on 3rd party CD) more useful for this
purpose.

There is no space to run “spin” on the target I want to debug for memory
leaking. Yeah, I can run it remotly. Spin is a great tool but I need check
heap size inside my application.

The description of malloc_g library says that there is function to check the
heap size but the function itself is not implemented.

Interesting… if you’re so tight on memory that you can’t even load spin,
I’d say you have a bigger problem. It only needs about 128k … Not having
that much essentially means you can’t run many other utilities, because
shell won’t be able to fork (unless you use some smaller shell, but even
then most utilities will require at least half as much).

You can modify the code to look only for certain pid instead of going
through all processes. Or just decrease the constant that defines max.
number of processes - the size of arrays used to keep & sort stuff depends
on it.

Igor,
where I can find spin source code? Did you use “electrict fance” ?
(any thoughts to share? )

Thanks,
Janusz.

The spin code is very helpful!
Do you know how to calculate the amount of used heap memory?

Regards,
Janusz.

There is no way to know externally what a given process is doing within its
heap space. The only way would be to overload malloc()/free() and friends
and have your own internal accounting.
