2004-03-11 Werner Koch <wk@gnupg.org>
* scdaemon.h (out_of_core): Removed. Replaced callers by standard
gpg_error function.
* apdu.c, iso7816.c, ccid-driver.c [GNUPG_SCD_MAIN_HEADER]: Allow
to include a header defined by the compiler. This helps us to
reuse the source in other software.
2004-03-10 Werner Koch <wk@gnupg.org>
* iso7816.c (iso7816_read_record): New arg SHORT_EF. Changed all
callers.
2004-02-18 Werner Koch <wk@gnupg.org>
* sc-investigate.c (main): Setup the used character set.
