CSocket::SendTo returns error when broadcasts???

Hi all,

When I used CSocket::SendTo(), with broadcast address(all 1s)

it returns the following error:

WSAEACCES The requested address is a broadcast address, but the appropriate flag was not set.

Then I used the flag MSG_DONTROUTE in sendTo function then also the same error is returned.

Then I tried with MSG_DONTROUTE|SO_DONTROUTE then it returned WSAEOPNOTSUPP.

Can any body tell me which flag should I use to broadcast an IP packet using CSocket.

thanks in advance.

Hi,


You´ll need to set a socket option to enable broadcast.


BOOL bEnableBroadcast(TRUE);

Socket.SetSockOpt(SO_BROADCAST, (const void*)&bEnableBroadcast, sizeof(BOOL));
