+
+Version:
+April 13, 2002
+
+ChangeLog:
+2002-04-13  Neal H Walfield  <neal@walfield.org>
+
+	* VERSION: Update to 20010413.
+	* Release version 20010413.
+	
+2002-04-13  Neal H Walfield  <neal@walfield.org>
+
+	* xgethostname.c (xgethostname): gethostname returns -1 on error,
+	not the error code.  There is no need to use realloc as it copies
+	the unused buffer.
+
+2001-08-03  Neal H Walfield  <neal@cs.uml.edu>
+
+	* VERSION: Update to 20010803.
+	* Release version 20010803.
+
+2001-08-03  Neal H Walfield  <neal@cs.uml.edu>
+
+	* Makefile: Make no assumptions about the make that the user
+	will be using.
+	* xgethostname.c (xgethostname): Be explicitly sure that the
+	returned buffer is NULL terminated.
+	Always compile in the while (err = ENAMETOOLONG) loop; this
+	may help to catch a very exotic implementation and does not
+	hurt anyone.
+
+2001-08-02  Neal H Walfield  <neal@cs.uml.edu>
+
+	* Release version 20010802.
+
+2001-08-01  Neal H Walfield  <neal@cs.uml.edu>
+
+	* Makefile: New file.
+	* README: New file.
+	* xgethostname.c (xgethostname) [!_SC_HOST_NAME_MAX]: Should
+	not be subject to this condition.
+	(xgethostname): If the system defines a limit < 256 and > 0,
+	do not artificially inflate it, rather, respect it.
+
+2001-07-30  Neal H Walfield  <neal@cs.uml.edu>
+
+	* REAMME: Move from here . . .
+	* xgethostname.2: to here.
+	Format it for man.
+
+2001-07-30  Neal H Walfield  <neal@cs.uml.edu>
+
+	* README: Fix grammer error.
+	* xgethostname.c: Likewise.

+
+	* Makefile: New file.
+

+.TH XGETHOSTNAME 2 "30 July 2001" "xgethostname"
+.SH NAME
+xgethostname \- get the host name.
+.SH
+SYNOPSIS
+.BI "char *xgethostname (void);"
+.SH DESCRIPTION
+The xhostname function is intended to replace
+.BR gethostname(2),
+a function used to access the host name.  The old interface is
+inflexable given that it assumes the existance of the
+.BR MAXHOSTNAMELEN
+macro, which neither
+.BR POSIX
+nor the proposed
+.BR "Single Unix Specification version 3"
+guarantee to be defined.
+.SH RETURN VALUE
+On success, a malloced, null terminated (possibly truncated)
+string containing the host name is returned.  On failure,
+.I NULL
+is returned and errno is set.
+.SH ERRORS
+.TP
+.BR ENOMEM
+Failed to allocate memory.
+.LP
+As 
+.BR xgethostname
+is really just a wrapper around your systems
+.BR gethostname (2),
+see that man page for additional details.
+.SH "SEE ALSO"
+.BR gethostname (2)
+.SH AUTHOR
+.BR xgethostname
+was written by Neal H Walfield  <neal@cs.uml.edu>.
