Question

调用函数初始化服务器时出现段错误

void initializeServer(int *serverSocket, struct sockaddr_in  *serverAddress) {
  int status;

  //Creating the server socket
  *serverSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
  if (serverSocket < 0) {
    printf("ERROR: Could not open socket. \n");
    exit(-1);
  }

  //Setting the server address
  memset(&serverAddress, 0, sizeof(&serverAddress)); //<- THIS
  serverAddress->sin_family = AF_INET;
  serverAddress->sin_addr.s_addr = htonl(INADDR_ANY);
  serverAddress->sin_port = htons((unsigned short) SERVER_PORT);

  //Binding the server socket
  status = bind(*serverSocket, (struct sockaddr *)serverAddress, sizeof(serverAddress));
  if(status < 0) {
    printf("ERROR: COULD NOT BIND SOCKET. \n");
    exit(-1);
  }

  //Setting the server up to listen for clients
  status = listen(*serverSocket, MAX_ROBOTS);
  if(status < 0) {
    printf("ERROR: COULD NOT LISTEN ON SOCKET.\n");
    exit(-1);
  }
}

此函数中某处出现段错误，而valgrind返回此错误：

使用大小为8的未初始化值
在0x1094F8：initializeServer 通过0x109624：主要

进程以信号11（SIGSEGV）的默认操作终止。地址为0x108F10的映射区域的权限错误在0x1094F8：initializeServer 通过0x109624：主要

堆很清楚，没有泄漏。我在main中测试了功能：

int main() {
  int *socket_;
  struct sockaddr_in *addr;

  initializeServer(socket_, addr); // <- ERROR HAPPENS HERE IF UNCOMMENTED

  printf("SERVER: Shutting down.\n");
}

真的为此感到困惑，我尝试了很多事情都没有用。 GDB，valgrind，重写。我似乎找不到错误的根源。

调用此函数时，段错误的原因是什么？
