Q: How to get physical memory size from user space without proc fs

[Denis Perchine]

Hello,

actually the question is in subj.
Problem is that there is a program which needs to know physical memory
size. This information is used to justify memory consumption as after some
swapping performance is drops dramatically, and it is better to finish.

I know that this is not the best idea, but it is assumed that this program
is the only one running on the machine.

I do not want to use proc as some people can just do not mount it.

Any comments, suggestions?

Thanks in advance.

Denis Perchine.
