linux-user: add SO_PEERCRED support for getsockopt
[qemu.git] / libcacard / vcard_emul_type.c
1 /*
2 * This file contains utility functions which abstract the different card
3 * types. The goal is that new card types can easily be added by simply
4 * changing this file and vcard_emul_type.h. It is currently not a requirement
5 * to dynamically add new card types.
6 *
7 * This work is licensed under the terms of the GNU LGPL, version 2.1 or later.
8 * See the COPYING.LIB file in the top-level directory.
