libnuma example from a presentation for a NUMA seminar

libnuma-ex.c

#include <numa.h>
#include <stdio.h>

int main(void)
{
        if(numa_available() < 0){
                printf("System does not support NUMA API!\n");
        }
        int n = numa_max_node();
        int size = 1024*1024;
        printf("There are %d nodes on your system\n", n + 1);
        void *mem = numa_alloc_onnode(size, n);
        if(mem == NULL){
                printf("could not allocate memory on node %d!\n", n);
        }
        numa_free(mem, size);

        if (numa_run_on_node(n) != 0) {
                printf("could not assign current thread to node %d!\n", n);
        }

        return 0;
}

can you maybe give a full working example?
