><P
>Builds a pattern using a list of objects, types and values.  Each
value to be entered in the pattern is specified with three arguments:</P
><P
></P
><OL
TYPE="1"
><LI
><P
>Object name, a string describing the property to be added.</P
></LI
><LI
><P
>Object type, one of the FcType enumerated values</P
></LI
><LI
><P
>Value, not an FcValue, but the raw type as passed to any of the
FcPatternAdd&#60;type&#62; functions.  Must match the type of the second
argument.</P
></LI
></OL
><P
>The argument list is terminated by a null object name, no object type nor
value need be passed for this.  The values are added to `pattern', if
`pattern' is null, a new pattern is created.  In either case, the pattern is
returned. Example</P
