Evo, baš sam nešto radio u vezi toga prethodnih dana... SERVER-KLIJENT komunikacija:

SERVER.CPP
------------

Code:
#include <stdio.h>
#include <stdlib.h>
#include <winsock2.h>

struct student{
    char ime[20];
    char prez[20];
    char matbr[15];
    char JMBG[15];
    short kz1;
    short kz2;
    short lab;
    float ukupno;
    short ocjena;
};

//treba linkati sa Ws2_32.lib
void win32stuff(){
    WSADATA wsaData;

    if(WSAStartup(MAKEWORD( 2, 2 ), &wsaData)){
        fprintf(stderr, "Ne mogu inicijalizirati mrezu\n");
        exit(1);
    }

    if ( LOBYTE( wsaData.wVersion ) != 2 || HIBYTE( wsaData.wVersion ) != 2 ) {
        /* Tell the user that we could not find a usable */
        /* WinSock DLL.                                  */

        fprintf(stderr, "Ne mogu inicijalizirati prave parametre\n");
        WSACleanup( );
        exit(1);
    }
}

int main(){
    int sock, lenght, bodovi = 0, ocjena = 0;
    struct sockaddr_in name, client;
    char buf[1000];

    win32stuff();

    sock=socket(AF_INET, SOCK_DGRAM, 0);

    if( sock<0 ){
        perror("Nece stvoriti socket\n");
        exit(1);
    }

    name.sin_family = AF_INET;
    name.sin_addr.s_addr = INADDR_ANY;
    name.sin_port=htons(10000);

    if( bind(sock, (struct sockaddr*) &name, sizeof(name) )<0 ){
        perror("Nece bindati\n");
        exit(1);
    }

    lenght=sizeof(name);

    if(getsockname(sock, (struct sockaddr*) &name, &lenght)<0){
        perror("Getsocket error\n");
        exit(1);
    }

    printf("Socket je na portu: %d, ja slusam:\n", ntohs(name.sin_port));

    while(1){
        if( recvfrom(sock, buf, 1024,0, (struct sockaddr*) &client, &lenght)<0 )
            perror("Nece ili nema sto za citati\n");
        else{
            printf("=>%s\n", buf);
            bodovi = 0;
            ocjena = 0;
                                      // obradi dobivene podatke
            // Rezultati(buf, &bodovi, &ocjena);
            sprintf(buf, "%s %d %d\n", buf, bodovi, ocjena);
            if( sendto(sock, buf, strlen(buf)+1, 0, (struct sockaddr*) &client, sizeof(name))<0 ){
                perror("Nece slati\n");
                exit(1);
            }
        }

        if(buf[0]=='e' && buf[1]=='n' && buf[2]=='d')
            break;
    }
    closesocket(sock);
    return 0;

Ovo sam radio za jedan predmet na faksu pa ćeš dosta toga moći i eliminirati :)
