FcPatternBuild3
Create patterns from arguments
Usage
#include <fontconfig/fontconfig.h>
FcPattern * FcPatternBuild (FcPattern *pattern, ...);
FcPattern * FcPatternVaBuild (FcPattern *pattern, va_list va);
void FcPatternVapBuild (FcPattern *result, FcPattern *pattern, va_list va);
Overview
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.
