glob() is not part of GCC and your question is not about GCC so it's
not relevant on this list.
The glob(3) man page explains it clearly. errfunc is not a function
that exists already, it's the name of one of the parameters in the
glob prototype, you have to pass an argument (or NULL) matching the
signature:
int (*errfunc) (const char *epath, int eerrno)
