Socket server:tcp multi-threaded version

One, the server side

#include <stdlib.h> #include <stdio.h> #include <string.h> #include <sys/socket.h> #include

        <netinet/in.h> int main (int argc, char*argv[]) {int SOCKFD = socket (af_inet, sock_stream, 0);
        struct sockaddr_in addrsrv;
        Bzero (&addrsrv, sizeof (struct sockaddr_in));
        ADDRSRV.SIN_ADDR.S_ADDR = htonl (Inaddr_any);
        addrsrv.sin_family = af_inet;
        Addrsrv.sin_port = htons (6000);

        Bind (SOCKFD, (struct sockaddr*) &addrsrv, sizeof (struct sockaddr));

        Listen (SOCKFD, 3);
        struct sockaddr_in addrconn;
        socklen_t len = sizeof (struct sockaddr_in);

                while (1) {int sockconn = accept (SOCKFD, (struct sockaddr*) &addrconn, &len);
                pid_t pid = fork ();
                        if (PID = = 0) {close (SOCKFD); while (1) {char buf[1024] = {0};
                                int n = read (Sockconn, buf, 1024);
                                if (n = = 0) {break;
                                printf ("Server recv:%s\n", buf);
                        Write (Sockconn, "Server Data", strlen ("Server data");
                Close (Sockconn);
                else if (PID > 0) {close (sockconn);

        } close (SOCKFD);
return 0; }

Second, client side

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <sys/socket.h >
#include <netinet/in.h>

int main (int argc, char*argv[])
{
        int sockfd = socket (af_inet, sock _stream, 0);

        struct sockaddr_in addrsrv;
        Bzero (&addrsrv, sizeof (struct sockaddr_in));
        ADDRSRV.SIN_ADDR.S_ADDR = inet_addr ("127.0.0.1");
        addrsrv.sin_family = af_inet;
        Addrsrv.sin_port = htons (6000);
        Connect (SOCKFD, (struct sockaddr*) &addrsrv, sizeof (struct sockaddr));

        Char temp[1024] = {0};
        while (1)
        {
                gets (temp);
                Write (SOCKFD, temp, strlen (temp));

                Char buf[1024] = {0};
                Read (SOCKFD, buf, 1024);
                printf ("Client recv:%s\n", buf);
        }


        Close (SOCKFD);

        return 0;
}
