Aggorno: con il seguente codice:

codice:
/*
# Linux
PCSC_CFLAGS := $(shell pkg-config --cflags libpcsclite)
LDFLAGS := $(shell pkg-config --libs libpcsclite)

CFLAGS += $(PCSC_CFLAGS)

sample: sample2.c

clean: rm -f sample2

#include <winscard.h>
#include <stdio.h>

#include <pcsclite.h>

#define CHECK(f, rv) \
 if (SCARD_S_SUCCESS != rv) \
 { \
  printf(f ": %s\n", pcsc_stringify_error(rv)); \
  return -1; \
 }\
 if (SCARD_S_SUCCESS == rv)\
 { \
  printf(f ": %s\n", pcsc_stringify_error(rv)); \
 }

		CHECK("SCardReleaseContext", rv);

Ottengo il seguente output:

codice:
 
(1). Establish context :
SCardEstablishContext: Command successful.
(2). Establish connection :
SCardConnect: Command successful.
(3). Begin transaction :
SCardBeginTransaction: Command successful.
(4). Send buffer :
SCardControl: Command successful.
Unknown error: 0x0000006E
(5). release transaction :
SCardEndTransaction: Command successful.
(6). Release connection :
SCardDisconnect: Command successful.
(7). Release context :
SCardReleaseContext: Command successful.
Adesso sarebbe carino capire se sbaglio i comandi inviati alla card con il mio buffer, o meglio cos'è questo:
Unknown error: 0x0000006E

Chi ne sapesse qualcosa farebbe cosa mooolto gradita a darmi una dritta..
