/* NAME

	xgethostname - get the host name.

   SYNOPSIS

   	char *xgethostname (void);

   DESCRIPTION

	The xhostname function is intended to replace gethostname(2), a
	function used to access the host name.  The old interface is
	inflexable given that it assumes the existance of the
	MAXHOSTNAMELEN macro, which neither POSIX nor the proposed
	Single Unix Specification version 3 guarantee to be defined.

   RETURN VALUE

	On success, a malloced, null terminated (possibly truncated)
	string containing the host name is returned.  On failure,
	NULL is returned and errno is set.
