Subject: private : figured out "Term: gethostbyname: Error 0" msg

The right thing to do is call herror() instead of perror() after a failed
get*by*() call.  Not all systems have it though (e.g. SunOS 4.x and 5.x
and NeXT 2.1 don't; Linux, Ultrix, and HCX/UX all do).  You might try
using the following definition and then using herror() instead.

#define I_STRING
#include "includes.h"


char *term_strherror(int err)
{
	static char string[80];
	switch (err) {
	case 0:
		strcpy(string, "Hostname lookup failed; no error reported");
		break;
#ifdef HOST_NOT_FOUND
	case HOST_NOT_FOUND:
		strcpy(string, "Host not found");
		break;
#endif
#ifdef TRY_AGAIN
	case TRY_AGAIN:
		strcpy(string,
		    "Non-authoritative `host not found', or server failed");
		break;
#endif
#ifdef NO_RECOVERY
	case NO_RECOVERY:
		strcpy(string,
		    "Non-recoverable hostname lookup error");
		break;
#endif
#ifdef NO_DATA
	case NO_DATA:
		strcpy(string,
		    "Valid name, no data record of requested type");
		break;
#endif
	default:
		sprintf(string, "Hostname lookup error %d", err);
		break;
	}
	return string;
