How to check the size of stack of a process?

Hi, every body.
I am a new user of Qnx4.24.
And i have questions as following:
1> How to check the size of stack of a process by calling a system
command?
2> Are there any ways by which we can know the size of memory used
by a certain process (as that what we can do in window OS)?

Thanks a lot and waiting for your answers. :wink:

โ€œsysmonโ€ ? It can monitor the cpu, memory, etc.

You can find it at ftp://ftp.qnx.com/usr/free/qnx4/os/utils/misc

Thank you, Noc.

Is there a QNX6 version? Or is there another utility I can use?

SPIN, I think it is available on the 3rd party repository.
