Checking the page size ?

Hi
How can I check the page size of my main memory ?
I've written the simple program in C, but this solution is not satisfying me.
#include <unistd.h>
int main(){
int a = getpagesize();
printf ("%d\n",a);
}
How can I check it in a different way(in linux)?

Thanks for help

Maybe you'll find some useful information in /proc/meminfo?

try this command -
getconf PAGESIZE
