FcPatternBuild(3)


NAME

   FcPatternBuild,  FcPatternVaBuild,  FcPatternVapBuild - Create patterns
   from arguments

SYNOPSIS

   #include <fontconfig/fontconfig.h>

   FcPattern * FcPatternBuild (FcPattern *pattern, ...);

   FcPattern * FcPatternVaBuild (FcPattern *pattern, va_list va);

   void FcPatternVapBuild (FcPattern *result, FcPattern *pattern, va_list va);

DESCRIPTION

   Builds a pattern using a list of objects, types and values. Each  value
   to be entered in the pattern is specified with three arguments:

   1.     Object name, a string describing the property to be added.

   2.     Object type, one of the FcType enumerated values

   3.     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.

   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

   pattern = FcPatternBuild (0, FC_FAMILY, FcTypeString, "Times", (char *) 0);

   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  result
   variable.
