FcPatternAddWeak - Add a value to a pattern with weak binding
#include <fontconfig.h> FcBool FcPatternAddWeak(FcPattern *p); (const char *object); (FcValue value); (FcBool append); .fi
FcPatternAddWeak is essentially the same as FcPatternAdd except that any values added to the list have binding weak instead of strong.
