Not in TIdTCPSocket, no.

Why do you think it is a problem?  Are you not expecting the server to
send you any data?

Why are you calling ioctlsocket() directly in the first place?  If you
want TIdTCPClient to check how many bytes are available from the
server without knowing ahead of time how many to expect, then you
should be calling its ReadFromStack() method instead, ie:

    ITcp->WriteInteger(3, true);
    int len = ITcp->ReadFromStack(true, 0, false);
    // len number of bytes have been placed into the InputBuffer if
any were available.

You are not checking the return value of ioctlsocket(), and you are
not initializing the len variable, so it is possible that the variable
contains some random value off of the stack that ioctlsocket() did not
overwrite.
