Hi All,
For freeing GMatchInfo struct, a special function is required. I'm not sure is
it possible to use g_autoptr in this case or no.
In GLib example
https://developer.gnome.org/glib/stable/glib-Perl-compatible-regular-expressions.html#g-regex-match,
g_match_info_free is used directly.
Best wishes,
Kostiantyn Kostiuk
