Yes i have used printf.. This is the code.
Code:
int main()
{
int sock;
int addr_len, bytes_read;
char recv_data[1024];
struct sockaddr_in server_addr , client_addr;
if ((sock = socket(AF_INET, SOCK_DGRAM, 0)) == -1) {
perror("Socket");
exit(1);
}
server_addr.sin_family = AF_INET;
server_addr.sin_port = htons(5000);
server_addr.sin_addr.s_addr = INADDR_ANY;
bzero(&(server_addr.sin_zero),8);
if (bind(sock,(struct sockaddr *)&server_addr,
sizeof(struct sockaddr)) == -1)
{
perror("Bind");
exit(1);
}
addr_len = sizeof(struct sockaddr);
printf("\nUDPServer Waiting for client on port 5000");
fflush(stdout);
while (1)
{
bytes_read = recvfrom(sock,recv_data,1024,0,
(struct sockaddr *)&client_addr, &addr_len);
recv_data[bytes_read] = '\0';
printf("\n(%s , %d) said : ",inet_ntoa(client_addr.sin_addr),
ntohs(client_addr.sin_port));
printf("%s", recv_data);
fflush(stdout);
}
return 0;
}
