C++ C中的ATONE会扰乱SENCLUTE GMS应用程序中的其他字符串

我们正在try 进行GMS服务器/客户端聊天. 在代码的这一部分使用atoi时遇到了问题

unserialize_tcp(buffer,&type, &grpname, &member_name, &received_addr, &received_port);
printf("1%s %s %s\n", grpname, member_name, received_addr);
addr = atoi(received_addr);
client.sin_addr.s_addr = addr;
client.sin_port = received_port;
printf("2%s %s \n", grpname, member_name);

输出是这样的 正如您所看到的那样，我们使用atoi后，成员名称失go 了原始价值

We didn't notify every member of the group  about the new member

这是unserialize_tcp函数

void unserialize_tcp(char* message, type_t *type, char** grpname, char** member_name, char** received_addr, int* received_port) {

    char msg[TCP_PACKET] = {'\0'};
    char *saveptr;
    char *ptr = message;
    char *delim = "_";
    int i;
    for (i = 0; ptr[i]; ptr[i] == '_' ? i++ : *ptr++);
    if (i != 4) {
        printf("Message corrupted\n");
        return;
    }
    strcpy(msg, message);
    *type = atoi(strtok_r(msg, delim, &saveptr));
    *grpname = strtok_r(NULL, delim, &saveptr);
    *member_name = strtok_r(NULL, delim, &saveptr);
    *received_addr = strtok_r(NULL, delim, &saveptr);
    *received_port = atoi(strtok_r(NULL, delim, &saveptr));
    

}

这是atoi问题起源的receive_worker线程

void *gms_receive_worker(void *args) {
  int i;
  char buffer[TCP_PACKET];
  char *grpname = (char*)calloc(16, sizeof(char));
  char* member_name = (char*)calloc(16, sizeof(char));

  char* received_addr = (char*)calloc(LENGTH_MSG, sizeof(char));
  char *msg;
  msg = (char*) malloc(sizeof(char)*TCP_PACKET);
  int received_port, addr;
  
  struct sockaddr_in client;
  while(!flag) {
    for (i=0; i< MAX_CLIENTS; i++) {
      memset(buffer, '\0',sizeof(buffer));
      if (recv(client_sockets[i], (char*)buffer, TCP_PACKET, MSG_WAITALL) < 0 ) {
            continue;
      }
      
      if(strlen(buffer) > 0) {

        addr = atoi(received_addr);
        client.sin_addr.s_addr = addr;

                exit(1);
            }
            continue;
          }
          printf(BOLDRED"Group %s lost the member %s \n"RESET, grpname, member_name);

          delete_gms_list(list, grpname, member_name, client);

当我们将atoi放入 comments 中时，member_list保留其原始值 这个问题非常奇怪，我们找不到解决方案. 任何 idea 都不胜感激，谢谢！

我们的期望: 好吧，我们没想到atoi会 destruct 另一个字符串的值，我们预计会看到相同的打印声明.但我们不
