WsKSendTo returns STATUS_INVALID_DEVICE_STATE: what does it mean?

Question
I am calling WsKSendTo on an opened socket (irp returns success in callback). But WskSendTo on that socket returns c0000184, what is referenced to as STATUS_INVALID_DEVICE_STATE. What kind of errors are addressed by this?
Did I miss something in the send routine?
psc->dstaddr.sin_family = AF_INET;
psc->dstaddr.sin_port = 0x6973; // big endian
psc->dstaddr.sin_addr.S_un.S_un_b.s_b1 = 0x02;
psc->dstaddr.sin_addr.S_un.S_un_b.s_b2 =
psc->dstaddr.sin_addr.S_un.S_un_b.s_b3 = 0x17;
psc->dstaddr.sin_addr.S_un.S_un_b.s_b4 = 0x0a;
// create IRP
psc->pirp = IoAllocateIrp(1, FALSE);
if(!psc->pirp){
DbgPrint("ShoutShout: IRP not allocated\n");
FreeShoutContext(psc);
return STATUS_UNSUCCESSFUL;
}
IoSetCompletionRoutine(
psc->pirp,
ShoutShoutComplete,
psc,
TRUE,
TRUE,
TRUE
);
// initiate send
const WSK_PROVIDER_DATAGRAM_DISPATCH *dispatch =
(PWSK_PROVIDER_DATAGRAM_DISPATCH)sockContext->socket->Dispatch;
status = dispatch->WskSendTo(
sockContext->socket, //PWSK_SOCKET
&psc->buf, //__in PWSK_BUF
NULL, // undocumented IN ULONG Flags,
(PSOCKADDR)&psc->dstaddr, // IN PSOCKADDR RemoteAddress OPTIONAL,
0, // IN SIZE_T ControlInfoLength,
0, // IN PCMSGHDR ControlInfo OPTIONAL,
psc->pirp); // IN PIRP Irp );
Afterwards status and pirp->IoStatus->Status contain afore mentioned error code and nothing is sent (or reaching the destination). Any suggestions?
Solution
c0000184 is returned if the socket is not fully initialised. For example if the socket is not yet bound to an address. The same problem existst in userland, always bind your socket! (Here using WskBind.)
It is also useful to synchronise the individual steps of the initialisation process: allocation of socket context, socket creation and binding using KEVENT (see KeInitializeEvent for a start).
