Question

Hi

I want to implement a TCP mudole in C++, I have the classes both TCPAssignment.cpp TCPAssignment.hpp , I need to complete some method in both of them to finish this homework

so I want to Implement my own socket()/bind()/getsockname()/close() ==> only this part

or at least socket()

these are the 2 classes.

TCPAssignment.cpp (/Desktop/abdulkarim/KENSv3-master/app/TestTCP) gedit En ) 16:04 Open Save ost.hpp> #include #include #include #include #include cerrno> «E/Networking/E.Packet.hpp> E/Networking/ENetworkutil.hpp> "TCPAssignment.hpp" nanespace E TCPAssignment::TCPAssignment (Host host) HostModule(" TCP", host), NetworkModule (this->getHostModuleNe host->getNetworkSystem()), SystenCallInterface(AF_INET, IPPROTO_TCP, host), NetworkLog(host->getNetworkSystem)) TinerModule(host->getsysten)) CPAssignment: TCPAssignment) void TCPAssignnent::initialize() void TCPAssignment::finalize() void TCPAssignnent::systencallback (UUID syscalluUID, int pid, const SystencallParaneter& param) switch(param.syscallNumber) case sOCKET: //this->syscall socket (syscalluuID, pid, param.param1 int, param.paran2 int) C++ Tab Width: 8 Ln 45, Col 2 INS

Explanation / Answer

The gneral syntax of getSockName is :

So as per the ablve need to implement the given method like below.

void TCPAssignment::syscall_getsockname(UUID syscallUUID, int pid, int sockfd,
   struct sockaddr *addr, socklen_t *addrlen){
        struct sockaddr_in *addr_in = (struct sockaddr_in *)addr;
   boolean found = false;
   for (int i = 0; i < (int)socketList.size(); i++)
   {
       if (socketList[i]->fd == sockfd)
       {
           addr_in->sin_family = socketList[i]->sin_family;
           addr_in->sin_port = socketList[i]->sin_port;
           addr_in->sin_addr = socketList[i]->sin_addr;
           *addrlen = socketList[i]->sin_addr_len;
           found = true;
           break;
       }
   }
   {
       returnSystemCall(syscallUUID, -1);
       return;
   }
   returnSystemCall(syscallUUID, 0);

}
