dtrace discuss - Dec 2005 - Getting number of bytes returned to application by free()?

Howdy,

I just got done reading the following article on using DTrace to debug C++ 
applications:

http://developer.sun.com/solaris/articles/dtrace_cc.html

And was curious if there is a way to use DTrace to grab the number of 
bytes free() returns to the application? The malloc(), free() and brk()
manual pages don''t provide a whole lot of info on what happens when
free() is called, and I was wondering if anyone has written some D to
grab this info? If not, I will start digging through the source code for 
malloc() and free() if they are available on opensolaris.org.

Thanks,
- Ryan
