C Socket 和 Omnet++ 之间的方法名称冲突

Collision of method name between C Socket & Omnet++

本文关键字：方法 冲突 之间 Socket Omnet++      更新时间：2023-10-16

我想在用 Omnet++ 完成的网络模拟中使用套接字，我在以下两者之间遇到方法名称冲突：

  • 套接字的 send（） 方法。
  • 由 Omnet++ 定义的 send（） 方法，允许模拟模块之间的味精交换。

编译器仅识别由 Omnet++ 定义的 send（） 方法。

我该如何解决它？

谢谢

为了更清楚，我将通过我的代码副本：

GeoTraCIMobility.cc（CPP代码）

#include <limits>
#include <iostream>
#include <sstream>
//#include <cstring>      // Needed for memset
//#include <sys/socket.h> // Needed for the socket functions
//#include <netdb.h>      // Needed for the socket functions
#include <sys/socket.h>
#include <arpa/inet.h>
#include <unistd.h>
#include "mobility/geoTraCI/GeoTraCIMobility.h"
Define_Module(GeoTraCIMobility);
namespace {
    const double MY_INFINITY = (std::numeric_limits<double>::has_infinity ? std::numeric_limits<double>::infinity() : std::numeric_limits<double>::max());
    double roadIdAsDouble(std::string road_id) {
        std::istringstream iss(road_id);
        double d;
        if (!(iss >> d)) return MY_INFINITY;
        return d;
    }
}
void GeoTraCIMobility::Statistics::initialize()
{
    firstRoadNumber = MY_INFINITY;
    startTime = simTime();
    totalTime = 0;
    stopTime = 0;
    minSpeed = MY_INFINITY;
    maxSpeed = -MY_INFINITY;
    totalDistance = 0;
    totalCO2Emission = 0;
}
//OTHERS FUNCTIONS
// Function that create a socket and send data
void GeoTraCIMobility::requestingFromPyServer()
{
    std::string HOST = "127.0.0.1";
    int PORT = 19999;
    int MAX_BUFFER = 1024;
      int connectionFd, rc, index = 0, limit = MAX_BUFFER;
      struct sockaddr_in servAddr, localAddr;
      char buffer[MAX_BUFFER+1];

      memset(&servAddr, 0, sizeof(servAddr));
      servAddr.sin_family = AF_INET;
      servAddr.sin_port = htons(PORT);
      servAddr.sin_addr.s_addr = inet_addr(HOST.c_str());
      // Create socket
      connectionFd = socket(AF_INET, SOCK_STREAM, 0);
      /* bind any port number */
      localAddr.sin_family = AF_INET;
      localAddr.sin_addr.s_addr = htonl(INADDR_ANY);
      localAddr.sin_port = htons(0);
      rc = bind(connectionFd,
          (struct sockaddr *) &localAddr, sizeof(localAddr));
      // Connect to Server
      connect(connectionFd,
          (struct sockaddr *)&servAddr, sizeof(servAddr));
      // Send request to Server
      std::string req= "ShortestPath_297162704_82660198";
      sprintf( buffer, "%s", req.c_str() );
      // UNRECOGNIZED SEND METHOD 
      send(connectionFd, buffer, strlen(buffer), 0 );
      // UNRECOGNIZED SEND METHOD
      close(connectionFd);
      printf("Client closed.n");
}

GeoTraCIMobility.cc 从 cSimpleModule 继承了以下发送方法：

cSimpleModule.h

/**
 * Sends a message through the gate given with its ID.
 */
int send(cMessage *msg, int gateid)  {return sendDelayed(msg, SIMTIME_ZERO, gateid);}
/**
 * Sends a message through the gate given with its name and index
 * (if multiple gate).
 */
int send(cMessage *msg, const char *gatename, int gateindex=-1)  {return sendDelayed(msg, SIMTIME_ZERO, gatename, gateindex);}
/**
 * Sends a message through the gate given with its pointer.
 */
int send(cMessage *msg, cGate *outputgate)  {return sendDelayed(msg, SIMTIME_ZERO, outputgate);}

使用 ::send(...) 访问 OMNeT++ 模型中的全局函数。否则，将调用从 cSimpleModule 固有的 send() 方法。
