How do I find the amount of memory installed on my QNX Neutrino system?

  • uname -a doesn't show it
  • top only shows how much memory is available
  • I've looked at pidin syspage without success
  • pidin mem shows all the used memory in gory detail

  • Awesome! I can't believe I didn't see that one. Your answer is better than mine. :-) Thanks a bunch. – kmort Jun 27 '14 at 12:23

The amount of free RAM is the size of "/proc" !

In your own program, you can write something like this :

#include <sys/stat.h>
struct stat buf;
if (stat("/proc", &buf) != -1) {
    printf("Mem free = %d\n", buf.st_size);
}
