NAME
       FcPatternAdd - Add a value to a pattern

SYNOPSIS
       #include <fontconfig/fontconfig.h>

       FcBool FcPatternAdd (FcPattern *p, const char *object, FcValue value,
       FcBool append);

DESCRIPTION
       Adds a single value to the list of values associated with the property
       named object.  If append is FcTrue, the value is added at the end of
       any existing list, otherwise it is inserted at the beginning.  value is
       saved (with FcValueSave) when inserted into the pattern so that the
       library retains no reference to any application-supplied data
       structure.
