SYNOPSIS

11
12       FcPattern * FcPatternBuild (FcPattern *pattern, ...);
13
14       FcPattern * FcPatternVaBuild (FcPattern *pattern, va_list va);
15
16       void FcPatternVapBuild (FcPattern *result, FcPattern *pattern, va_list va);

DESCRIPTION

19       Builds a pattern using a list of objects, types and values. Each  value
20       to be entered in the pattern is specified with three arguments:
21
22       1.     Object name, a string describing the property to be added.
23
24       2.     Object type, one of the FcType enumerated values
25
26       3.     Value,  not an FcValue, but the raw type as passed to any of the
27              FcPatternAdd<type> functions. Must match the type of the  second
28              argument.
29
30       The  argument  list is terminated by a null object name, no object type
31       nor value need be passed for this. The values are added  to  `pattern',
32       if  `pattern'  is  null,  a new pattern is created. In either case, the
33       pattern is returned. Example
34
35       pattern = FcPatternBuild (0, FC_FAMILY, FcTypeString, "Times", (char *) 0);
36
37
38       FcPatternVaBuild is used when the arguments are already in the form  of
39       a  varargs  value.  FcPatternVapBuild  is  a  macro  version  of FcPat‐
40       ternVaBuild which returns its result directly in the result variable.
