/************************************************************
 *
 *	helloClient.c
 *
 *	Adapted from Douglas Comer's "Internetworking with TCP/IP"
 *	by Jeff Ondich and Lauren Jantz, summer 1995.
 *
 *	This client is half of a sort of "hello world"
 *	client/server pair.  The client makes a connection
 *	to the server (at the HOST_NAME and PORT_NUMBER
 *	defined in hello.h), and the server sends back
 *	a snotty null-terminated character string.  The
 *	client prints this message to its own stdout.
 *
 *	Note that the protocol is exceedingly simple:
 *
 *		1. Client initiates connection
 *		2. Server sends message, null-terminated
 *		3. Server closes connection
 *
 *	In particular, the client never sends any actual
 *	text to the server.  If you want your client to
 *	talk to the server, you'll need to design a more
 *	complicated protocol, and the client will use
 *	write() to send data to the server.
