Collision of method name between C Socket & Omnet++ - c++

Question

I want to use sockets inside my network simulation done with Omnet++, i am getting a collision of method name between:
send() method of Socket.
send() method defined by Omnet++, that allow
exchange of msg between simulation modules.
The compiler recognize only send() method defined by Omnet++.
How can i resolve it ?
Thank you,
EDIT
In order to make it more clear, i will past a copy of my code:
GeoTraCIMobility.cc (CPP Code)
#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 inherits from cSimpleModule the following send methods:
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);}

Answer 1

Use ::send(...) to access the global function in an OMNeT++ model. Otherwise the send() method inhertited from the cSimpleModule will be called.
