man FcPatternAdd-Type (Fonctions bibliothèques) - Add a typed value to a pattern
NAME
FcPatternAddInteger, FcPatternAddDouble, FcPatternAddString, FcPatternAddMatrix, FcPatternAddCharSet, FcPatternAddBool - Add a typed value to a pattern
SYNOPSIS
#include <fontconfig.h> FcBool FcPatternAddInteger (FcPattern *p, const char *object, inti); FcBool FcPatternAddDouble (FcPattern *p, const char *object, doubled); FcBool FcPatternAddString (FcPattern *p, const char *object, const char *s); FcBool FcPatternAddMatrix (FcPattern *p, const char *object, const FcMatrix *m); FcBool FcPatternAddCharSet (FcPattern *p, const char *object, const FcCharSet *c); FcBool FcPatternAddBool (FcPattern *p, const char *object, FcBoolb);
DESCRIPTION
These are all convenience functions that insert objects of the specified type into the pattern. Use these in preference to FcPatternAdd as they will provide compile-time typechecking. These all append values to any existing list of values.
