FcCharSetMerge
Name
FcCharSetMerge -- Merge charsets
Synopsis
#include <fontconfig/fontconfig.h>
FcBool FcCharSetMerge(FcCharSet *a, const FcCharSet *b, FcBool *changed);
Description
Adds all chars in b to a.
In other words, this is an in-place version of FcCharSetUnion.
If changed is not NULL, then it returns whether any new
chars from b were added to a.
Returns FcFalse on failure, either when a is a constant
set or from running out of memory.
