AW: [En-Nut-Discussion] Problems with NutTcpReceive

[Ernst Stippl]

Hi Markus!

I am not especially good at C, but try  

if (( data = NutTcpReceive(sock,in_data,sizeof(in_data)-1))!= 0)

instead of

if ( data = NutTcpReceive(sock,in_data,sizeof(in_data)-1)!= 0)

Do you recognize the additional braces? Maybe they influence the sequence in
which the statemant is executed.

regards
Ernst

Betreff: [En-Nut-Discussion] Problems with NutTcpReceive

Hi, I am from germany my english isn´t so good

I have Problems withe the function " NutTcpReceive" or "NutTcpDeviceRead"

I have in my program a while loop.
I ask, have the PIND changed
and then I ask,

if ( data = NutTcpReceive(sock,in_data,sizeof(in_data)-1)!= 0)
  {
	if (in_data == ....)
		{
			do anything;
		}
	if (in_data == ....)
	{
			do anything
	}

	}

The while loop works, but ist stops at the function ---- if ( data =
NutTcpReceive(sock,in_data,sizeof(in_data)-1)!= 0)----

if I receive an String on "sock" the loop does work one times more and stops
at the same position again and again.

Can someone help me?

Thanks

Markus
