wxSocketBase: Exiting after reading data Topic is solved

In that case the only thing I can propose - provide SSCCE for reproducing behaviour.

I don't do anything peculiar than information I have provided. All I do is:
1. create wxSocketClient passing no argume.
2. Set Notify flags
3. Write to Socket
4. In response to Socket read event I just call the method we have been discussing.

Nothing peculiar as you can see!

If you are responding to a wxSOCKET_INPUT event, then you can simply use Read(buffer, len) to read all available bytes and return. I am pretty sure that Read is guaranteed to get something if a wxSOCKET_INPUT event has occurred.

The following works for me in both Windows and Linux.

Code: Select all

void MainFrame::OnSocketEvent(wxSocketEvent& event)
{
    wxLogMessage("OnSocketEvent: ");
    wxSocketBase* sockBase = event.GetSocket();

    // Process the event.
    switch (event.GetSocketEvent())
    {
        case wxSOCKET_INPUT:
        {
            wxLogMessage("wxSOCKET_INPUT\n"); 

            char buf[256];
            
            // Read the message
            wxUint32 lenRd = sockBase->Read(buf, 256).LastCount();

            if (!lenRd) 
            {
                wxLogMessage("Failed to read any data.\n");
                return;
            }
            
            else 
            {
                wxLogMessage("Read %d bytes.\n", lenRd);
            }

            wxLogMessage("Rx: %s \n", wxString::FromUTF8(buf, lenRd));
            break;
        }
      ...

That sounds great except I don't know buffer size. May be I have to make it the biggest possible. I will try that option too!

This solves my issue.
Thanks everyone who helped!
