get http code without blocking the program in a while loop.

For a project i need a hardwired connection with ethernet, for which i am using the W5500 connected to my esp32s2. The posting works without any isues, but i would like to have the httpcode back. This way i know if the command has succesfully been received and handled.

The function i use to post the commands is seen below. Anybody that has a idea that won't block my program but gets met the httpcode?

bool httpSendRequest(String type, String JsonData)
{
  Serial.print("  STATIC assigned IP ");
  Serial.println(Ethernet.localIP());
  if (client.connect(TV_ip, TV_port))
  {
    client.println( type + url + "HTTP/1.1");
    client.println("Host: " + String(TV_ip) + ":" + String(TV_port));
    client.println("Content-Type: application/x-www-form-urlencoded");
    client.println("User-Agent: " + userAgent);
    client.print("Content-Length: ");
    client.println(JsonData.length());
    client.println();
    client.println(JsonData);
    client.println();

    return true;
  }
  else {
    // if you didn't get a connection to the server:
    Serial.println("connection failed");
    return false;
  }
}
