The FcPattern contents are opaque.  However, what you probably want to
do is to iterate over the array in the FcFontSet and call e.g.
FcPatternGetString (p, FC_FAMILY, 0, &s); to get the family name of an
FcPattern (returned in s).

One way of going from an FcPattern to a string is FcNameUnparse,
although this is probably not the string you want.

You may want to consult fc-list/fc-list.c
