Memory size?

[Joerg Schwerdtfeger]

Hi folks,

how can I determine the total main-memory size and the size of free
memory available in bytes?

I tried to use mallinfo() from malloc.h - resulting some strange values
in Windows (cygwin, gcc 3.3.1) and always 0 in Linux (2.4.22, gcc
3.3.2).

Thanks in advance,
Jörg

What a whiner. Until we finish the Cray-INF with unlimited virtual memory,
how best to deal with running out of resources? Unceremoniously kill
everyone because that way we get uniform behaviour? Or give programs
an opportunity for a graceful exit, if they choose to exploit it?

The latter. And therefore, when you can't give a program the memory it
asks for, you have it _return a null pointer_, not pretend to be in
happy-happy land and _then_ unceremoniously kill it or random other
programs just because you can.
