Writing with Server in C++

<p>I am programming a server-client service, the client is in Java and the Server is in C++, but when I try to write by the Server to the Client, he does not sends the message, only when i close the socket, the server sends the message and the client reads it. Here is the Server Code:</p><pre><br /><code>#include<stdio.h><br />#include<stdlib.h><br />#include<sstream><br />#include<string><br />#include<netdb.h><br />#include<netinet/in.h><br />#include<string.h><br />#include<iostream><br />#include<sys/types.h><br />#include<sys/socket.h><br />#include<arpa/inet.h><br />#include<unistd.h><br /><br /><br />using namespace std;<br /><br />void doprocessing (int sock, int cliente);<br />void sendM(int socket,int client);<br /><br />int main(int argc, char *argv[]) {<br /> int sockfd, newsockfd, portno,cliente;<br /> char buffer[256];<br /> struct sockaddr_in serv_addr, cli_addr;<br /> int n, pid;<br /> socklen_t clilen;<br /><br /><br /> sockfd = socket(AF_INET, SOCK_STREAM, 0);<br /><br /> if (sockfd < 0) {<br /> perror("ERROR opening socket");<br /> exit(1);<br /> }<br /><br /> bzero((char *) &serv_addr, sizeof(serv_addr));<br /> portno = 8080;<br /><br /> serv_addr.sin_family = AF_INET;<br /> serv_addr.sin_addr.s_addr = INADDR_ANY;<br /> serv_addr.sin_port = htons(portno);<br /><br /> if (bind(sockfd, (struct sockaddr *) &serv_addr, sizeof(serv_addr)) < 0) {<br /> perror("ERROR on binding");<br /> exit(1);<br /> }<br /><br /><br /> listen(sockfd,5);<br /> clilen = sizeof(cli_addr);<br /> cout<<"Servidor Iniciado1..."<<endl;<br /><br /> while (1) {<br /> newsockfd = accept(sockfd, (struct sockaddr *) &cli_addr, &clilen);<br /> cliente=cliente+1;<br /> if (newsockfd < 0) {<br /> perror("ERROR aceptando conexion");<br /> exit(1);<br /> }<br /> /* Create child process */<br /> pid = fork();<br /><br /> if (pid < 0) {<br /> perror("ERROR on fork");<br /> exit(1);<br /> }<br /><br /> if (pid == 0) {<br /><br /> cout<<"Nueva conexion "<<cliente<<endl;<br /> close(sockfd);<br /> doprocessing(newsockfd,cliente);<br /> exit(0);<br /> }<br /> else {<br /> close(newsockfd);<br /> }<br /><br /> }<br />}<br /><br />void doprocessing (int sock, int cliente1) {<br /> int n;<br /> char buffer1[256];<br /> bzero(buffer1,256);<br /> n = read(sock,buffer1,255);<br /> n=1;<br /> if (n < 0) {<br /> perror("ERROR leyendo el socket");<br /> exit(1);<br /> }<br /> cout<<"Mensaje de cliente "<<cliente1<<":"<<buffer1<<endl;<br /> sendM(sock,cliente1);<br /> if (n < 0) {<br /> perror("ERROR escribiendo al socket");<br /> exit(1);<br /> }<br /><br />}<br /><br />void sendM(int socket, int client){<br /> std :: string buff;<br /> int n;<br /> cout << "\nServidor: ";<br /> cin >> buff;<br /> n=send(socket, buff.data(), buff.length(),0);<br /> cout<<buff.data()<<"\n";<br /> cout<<n<<endl;<br /> if(n<0){<br /> cout<<"Error enviando respuesta"<<endl;<br /> }<br /> doprocessing(socket,client);<br />}<br /></code><br /></pre><br /><h2>Click here view more answers <a href="http://ift.tt/1L7Se1F">http://ift.tt/1L7Se1F</a></h2>
