programatically read 'size' shown in top on SunOS?

How can the 'size' of a process shown by 'top', be read programatically in ‘C’ on SunOS?

I'm fixing a memory leak in a large (20,000 lines) ‘C’ program on Solaris.

It can be found in /proc/<pid>/psinfo.
Look for psinfo in in the proc manual page:

Code:

man -s 4 proc

Google for "Solaris debug memory leaks" and you'll find several potentially useful tips, including:

UMEM_DEBUG:

Dtrace:

If this is a commercial project (i.e. if you have a budget, and somebody who can cut a purchase order), I would *definitely* consider getting Purify:

To track down memory leaks, you can also use Sun Studio dbx rtc extension.
