I want to find out how many memory is used by a process P. Process P
is running on Solaris 8 sun workstation. Basically, I want to know if
there is memory leaking from process P. Could someone tell me how to
do this?
Thanks

First look at your code carefully to check whether you release theQuote:> Basically, I want to know if

Memory leak detecting tools like Purify can help you more. If you want to
go for differrent tools like purify, then :-
www.cs.colorado.edu/homes/zorn/public_html/MallocDebug.html will give you
the answer.

My program uses STL List and Map classes and I put template class into
these Lists. When I monitor the output of vmstat for my workstation,
although the system may regain small portion of the memory, swap and
free memory have a trend to decrease , but I don't know which process
leaks memory.
Thanks you all for your help.

5. What function could I use to find the size of memory usage by the process?
7. question about process memory usage and process memory limits
8. Can,t Use display through remote login: help!!
9. How to get virtual memory size and working set size of a process on AIX ?
10. How can a user find out how much memory his/her process is using?
11. how do I find out what programs/processes are using most resources/memory?
12. memory leaks by shared memory and fork
13. Sun workshop memory monitor does not detect all memory leak
