c - 错误: Expected ')' before 'packet'

Question

我有这个代码:

void addSpammer(honeypot_command_packet packet){
          hashtable_put(spammer_table, packet->ip_source_address_big_endian, packet);
      }
    void addVulnerable( honeypot_command_packet packet){
      hashtable_put(vulnerable_table, packet->udp_dest_port_big_endian, packet);
    }

    void addEvil( honeypot_command_packet packet){
      hashtable_put(evil_table, packet, packet);
    }

    void rmSpammer(honeypot_command_packet packet){
      hashtable_remove(spammer_table, packet->ip_source_address_big_endian);
    }
     
    void rmVulnerable(honeypot_command_packet packet){
      hashtable_remove(vulnerable_table, packet->udp_dest_port_big_endian);
    }

    void rmEvil(honeypot_command_packet packet){
      hashtable_remove(evil_table, packet);
    }

    void print_stats(){
      puts("Printing stats...");
    }

    void handle_packet_table(honeypot_command_packet pack){

            if(pack->secret_big_endian == HONEYPOT_SECRET){
                    
                    printf_m("This is a command packet %x \n", pack->cmd);
                    
                    if(pack->cmd == HONEYPOT_ADD_SPAMMER){
                            // handle addint a spammer
                            addSpammer(pack);
                            
                    }else if(pack->cmd == HONEYPOT_ADD_EVIL){
                            // handle adding an evil packet hash
                             addEvil(pack);
                            
                    }else if(pack->cmd == HONEYPOT_ADD_VULNERABLE){
                            // handle addint a vunlerable port
                            addVulnerable(pack);
                            
                    }else if(pack->cmd == HONEYPOT_DEL_SPAMMER){
                            // handle removing a spammer
                            rmSpammer(ip_source_address_big_endian);
                            
                    }else if(pack->cmd == HONEYPOT_DEL_EVIL ){
                            //handle removing an evil packet
                            rmEvil(ip_source_address_big_endian);
                            
                    }else if(pack->cmd == HONEYPOT_DEL_VULNERABLE ){
                            //handle removing a vulnurable port
                            rmVulnerable(udp_dest_port_big_endian);
                            
                    }else if(pack->cmd == HONEYPOT_PRINT){
                            print_stats();
                            //handle printing from the packet
                    }else{
                            printf_m("there is a problem with the data field \n");
                    }
            
            }
            else{
              // the packet is not anything
              //check if it is in any of the lists then increment the number of packets processed
              void* *item;
              if (hashtable_get(spammer_table, pack->ip_source_address_big_endian, *item) == 0){
                addSpammer(pack);
              }

              if (hashtable_get(vulnerable_table, pack->udp_dest_port_big_endian, *item) == 0){
                addVulnerable(pack);
              }

              if (hashtable_get(evil_table, pack, *item) == 0){
                addEvil(pack);
              }
              else{
                hashtable_put(good_table, pack, pack);
              }
            }

            packets_arrived++;
            bytes_arrived+=sizeof(pack);
    }

我收到以下错误:

network.c:94: error: expected ‘)’ before ‘packet’

network.c:98: error: expected ‘)’ before ‘packet’

network.c:102: error: expected ‘)’ before ‘packet’

network.c:106: error: expected ‘)’ before ‘packet’

network.c:110: error: expected ‘)’ before ‘packet’

network.c:114: error: expected ‘)’ before ‘packet’

network.c:122: error: expected ‘)’ before ‘pack’

我不太确定如何解决这些问题，我检查了括号是否已经匹配。

问题是您正在尝试使用 honeypot_command_packet 类型，但您之前显然没有定义该类型。也许您缺少所需的 #include，或者类型需要限定为 some_namespace::hoenypot_command_packet
