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.
