* $Log: encode.c,v $
+ * Revision 1.4 2002/01/22 23:28:07 jongfoster
+ * Adding convenience function html_encode_and_free_original()
+ * Making all functions accept NULL paramaters - in this case, they
+ * simply return NULL. This allows error-checking to be deferred.
+ *
* Revision 1.3 2001/11/13 00:16:40 jongfoster
* Replacing references to malloc.h with the standard stdlib.h
* (See ANSI or K&R 2nd Ed)
* Returns : The integer value, or -1 for non-hex characters.
