How to post a message on the site?

Question

C++ / C#

I use libcurl, one needs to post a message to the tag on the site, the other reads it, and vice versa, if the message number is already in textedit, then it is not added and so every second it checks the site yukoz here it receives data
<p>message=#%some_number%,%some_message%</p>

size_t write_data(char *ptr, size_t size, size_t nmemb, FILE* data)
{
  return fwrite(ptr, size, nmemb, data);
}
void__ Math::SetRotate()
{
  if(!Drum_->GetAllRoll()&&GetCredits()>=GetTotalBet()&&GetWin_()==0)
    {
#if netsupport==1
        /*
    Con_->SetBuf("Give Me Next Datagramm",0);
        Con_->Snd(0);
    Con_->ClearBuf(0);
        Con_->Recv(0);
        Drum_->SetBuffer(Con_->GetBuf(0));
        Con_->ClearBuf(0);
