I have created a namespace (below sample program) and how can I create a network name space.

#include <sys/types.h>
#include <unistd.h>

struct clone_arg {
    int (*fn)(void *);
    void *arg;

static int do_start(void *data)

static int do_clone(void *arg)
    struct clone_arg *clone_arg = arg;
                printf("inside do_clone");
                return clone_arg->fn(clone_arg->arg);

int main()
    int (*fn)(void *) ;
    struct clone_arg clone_arg ={.fn=fn,.arg=NULL  };
                long stack_size = sysconf(_SC_PAGESIZE);
    void *stack = alloca(stack_size) + stack_size;
                int flags= CLONE_NEWNS;
    pid_t ret;
                printf("inside main");
    ret = clone(do_clone, stack, flags ,&clone_arg);

return 1;
