Find amount of installed memory on QNX system

问题

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

回答1:

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);
}
