Linux下的C问题.....

有一源程序:
#include <stdio.h>;
#include <signal.h>;
#include <unistd.h>;
void waiting(),stop();
int wait_mark;
main()
{
int p1,p2;
while((p1=fork())==-1);
if(p1>;0)
{
while((p2=fork())==-1);
if(p2>;0)
{
  wait_mark=1;
  signal(SIGINT,stop);
waiting(0);
kill(p1,16);
kill(p2,17);
wait(0);
wait(0);
printf("parent process is killed!\n";
exit(0);
}
else
{
wait_mark=1;
signal(17,stop);
waiting();
lockf(stdout,1,0);
printf("child process 2 is killed by parent!\n";
lockf(stdout,0,0);
exit(0);
}
}
else
{
wait_mark=1;
signal(16,stop);
waiting();
lockf(stdout,1,0);
printf("child process 1 is killed by parent!\n";
lockf(stdout,0,0);
exit(0);
}
}
void waiting()
{
  while (wait_mark!=0);
}
void stop()
{
   wait_mark=0;
}
这个程序是教材上的，我刚学操作系统是个菜鸟，不明白为什么它运行不起来，请高手指教~或许书上哪里错了什么吧~~~
