Moin,
hatte gerade nichts anderes vor.
Dein Code mit leichter Änderung.
| C++: |
#include <winsock2.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <iphlpapi.h>
#include <errno.h>
#pragma argsused
int main(void)
{
WSADATA wsaData;
SOCKET upnp_sock;
int i=0;
int j=0;
int bytes=0;
int remo_addr_len;
struct sockaddr_in remo_addr;
struct sockaddr_in listen_addr;
char buff[500];
WSAStartup(MAKEWORD(2, 2), &wsaData) ;
upnp_sock = WSASocket(AF_INET, SOCK_DGRAM, IPPROTO_UDP, NULL, 0, 0);
printf("\nSOCKET ERROR:%i\n",WSAGetLastError());
listen_addr.sin_addr.s_addr = inet_addr("127.0.0.1");
listen_addr.sin_port = htons(1905);
listen_addr.sin_family = AF_INET;
bind(upnp_sock, (struct sockaddr*) &listen_addr, sizeof(listen_addr));
printf("\nBIND ERROR:%i\n",WSAGetLastError());
printf("Versuche irgendetwas zu empfangen...\n");
remo_addr_len = sizeof(remo_addr);
i=1;
while (j<10)
{
bytes=recvfrom(upnp_sock, buff, sizeof(buff), 0, (struct sockaddr *) &remo_addr, &remo_addr_len);
if (bytes == -1)
{
printf("\nRECVFROMERROR:%i\n",WSAGetLastError());
}
printf("Bytes:%d\n", bytes);
buff[bytes]='\0';
bytes=0;
// Ausgabe des Durchlauf und Inhalt von buff.
printf("%d . %s",i, buff);
/*while (buff[i] != '\0' )
{
printf("%s", buff);
}*/
printf("\n\n#############\n\n");
// Bestätigung an Client senden.
sendto( upnp_sock, "OKAY", 5, 0, (SOCKADDR*)&remo_addr, remo_addr_len);
memset(&buff, '\0', sizeof(buff)-1);
j++;
i++;
}
printf("Feddish\n");
closesocket (upnp_sock);
getchar();
return 0;
}

Sollte jetzt auch bei Dir funktionieren. |

hat nichts mit ANSI C zu tun
