how to send host name to client?

[beginner123]

I have a server and client program. The server sends its IP address to a master web server. The client then reads this list and displays the IP addresses in a listbox. The client can then select a server and connect to it. But i also want to display the server's host name next to the IP address in the client listbox.

here is the code to send the IP address:

  char ac[80];
	if (gethostname(ac, sizeof(ac)) == SOCKET_ERROR) 
	{
		printf("Error when getting local host name: ", WSAGetLastError()); 
		exit(0);
	}
	
	struct hostent *phe = gethostbyname(ac);
	if (phe == 0) 
	{
		printf("Error: ", WSAGetLastError()); 
		exit(0);
	}

	struct in_addr addr;
	memcpy(&addr, phe->h_addr_list[0], sizeof(struct in_addr)); // use the first ip-address
	printf("IP used by Server: %s\n", inet_ntoa(addr)); // inet_ntoa(addr) provides the local address.
	MyIP = inet_ntoa(addr);

	char SendBuf[32];
	sprintf(SendBuf, "%hhu|%s", cAddIP, MyIP);   // Send the server the IP
	WebPost(WEBSITE, WEBPAGE, SendBuf, 0);

what do i need to do to also send the host name?

You already have the local hostname, it was returned to you in Line 2 of this code snip. You should send it the same way you are sending the IP. It would help if you posted the code for "WebPost".
