Heap size of a process

[mysterious]

can anybody tell me how to get heap size taken by a process and maximum heap size allowed for the process...

using pmap <pid> does not list the [heap] memory information of that process.

also tried using /proc/<pid>/maps

Thanks in advance...

Linux find the memory used by a program / process using pmap command

yes, used pmap <pid> command, but could not see heap memory taken by the process.

Other reason may be the process is not using heap. (it is third party application).

but running same process under solaris, shows utilization of heap memory.

Any ideas, if i can use any other command?

Forgot to mention i am using Red Hat Linux 2.6.9 x86_64

Thanks...
