Na zaliczenie mam do napisania aplikacje typu Klient-Server na socketach, udalo mi sie cos takiego splodzic. Potrzebuje dopisac do tego logowanie informacji do pliku takich jak: tresc wiadomosci, od kogo i kedy. Czy moglby ktos mi w tym pomoc ??
Probowalem dodac biblioteke <fstream> wywala mi ze nie moze jej znalesc .....
Ponizej wklejam kod serverka:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <errno.h>
#include <string.h>
#include <sys/types.h>

#include <netinet/in.h>
#include <arpa/inet.h>
#include "logi.h"
//#define MYPORT 22 // the port users will be connecting to
#define MAXBUFLEN 500
int main()
{
int sockfd;
struct sockaddr_in my_addr; // my address information
struct sockaddr_in their_addr; // connector's address information
int addr_len, numbytes;
char buf[MAXBUFLEN];
int myport;
printf("Set Port Number: "); // get port number to work
scanf ("%d", &myport);
if ((sockfd = socket(AF_INET, SOCK_DGRAM, 0)) == -1) {
perror("socket");
exit(1);
}
my_addr.sin_family = AF_INET; // host byte order
my_addr.sin_port = htons(myport); // short, network byte order
my_addr.sin_addr.s_addr = INADDR_ANY; // automatically fill with my IP
memset(&(my_addr.sin_zero), '\0', 8); // zero the rest of the struct
if (bind(sockfd, (struct sockaddr *)&my_addr,
sizeof(struct sockaddr)) == -1) {
perror("bind");
exit(1);
}
while(1){
addr_len = sizeof(struct sockaddr);
if ((numbytes=recvfrom(sockfd,buf, MAXBUFLEN-1, 0,
(struct sockaddr *)&their_addr, &addr_len)) == -1) {
perror("recvfrom");
exit(1);
}
printf("\n\a");
printf("\033[1;31mgot packet from\033[0;0m \033[1;33m %s \033[0;0m \n",inet_ntoa(their_addr.sin_addr));
