WOW i did not know this

int main(int argc, char **argv)
{
	uint8_t *shared_memory = mmap(NULL, PAGESIZE,
																PROT_READ | PROT_WRITE,
																MAP_SHARED | MAP_ANONYMOUS, -1, 0);
	*shared_memory = 34;
	if (fork() == 0)
	{
		*shared_memory = 15;
		v = 80;
	} else {
		wait(NULL);
	}
	printf("Not shared. %i\\n", v);
	printf("Shared. %i\\n", shared_memory);
}
