-@PURPOSE@ Add a value to a pattern
-@DESC@
-Adds a single value to the list of values associated with the property named
-`object<parameter>. If `append</parameter> is FcTrue, the value is added at the end of any
-existing list, otherwise it is inserted at the beginning. `value' is saved
-(with FcValueSave) when inserted into the pattern so that the library

-@PURPOSE@ Create patterns from arguments
-@DESC@
-Builds a pattern using a list of objects, types and values. Each
-value to be entered in the pattern is specified with three arguments:
-</para>
-<orderedlist>
-<listitem><para>
-Object name, a string describing the property to be added.
-</para></listitem><listitem><para>
-Object type, one of the FcType enumerated values
-</para></listitem><listitem><para>
-Value, not an FcValue, but the raw type as passed to any of the
-FcPatternAdd<type> functions. Must match the type of the second
-argument.
-</para></listitem>
-</orderedlist>
-<para>
-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
-</para>
-<programlisting>
-pattern = FcPatternBuild (0, FC_FAMILY, FcTypeString, "Times", (char *) 0);
-</programlisting>
-<para>
-FcPatternVaBuild is used when the arguments are already in the form of a
-varargs value. FcPatternVapBuild is a macro version of FcPatternVaBuild
-which returns its result directly in the <parameter>result</parameter>
-variable.
