* in main():
** errx()/err()/return -> exit()
** return values -> EXIT_SUCCESS & EXIT_FAILURE
* out of main:
** err()/errx()/exit() -> return
** change retval from size_t to int to allow returning errors
** don't use EXIT_SUCCESS / EXIT_FAILURE as retvals
* add nfc_close() & nfc_exit() to exit() on errors
* add missing fclose() on errors
* add missing test if (pnd == NULL)
* unify style if (pnd == / != NULL)
* remove goto's
* few related fixes
* remove if(pnd!=NULL) test on nfc_close() calls
- nfc_device is now an opaque type;
- PN53x specific errors are not public anymore;
- nfc_device_name() renamed to nfc_device_get_name() for the sake of consistency;
- examples/*, utils/* uses the new nfc_device_get_name() function instead of access directly to struct's content;
- new error defined: NFC_ERFTRANS for notifying about RF transmission error, its used by mifare.c to detect permissions error on mifare;
- drivers initiator_transceive_bytes() function now returns libnfc's error code on failure (<0), and received bytes count on success (>=0);
- remove some unused errors.
- Provide a nfc_get_default_device() that allow to grab the connstring stored
in LIBNFC_DEFAULT_DEVICE environnement variable or returns the first
available device if not set;
- nfc_connect(NULL) now takes the default device (see
nfc_get_default_device());
- Removes nfc_driver_desc_t from public types
- Defines nfc_connstring as char[1024]
- examples/*: use nfc_connstring
- examples/nfc-poll: now uses only the default device (instead of all devices
availables)
- Removes parse_args() from nfc-utils.[hc]
New Issue
Summary: Remove nfc-message.h file from installed ones
nfc-message.h provide some usefull debugging macros but I am not sure that these macros have to be installed with other files.
- New API function append_iso14443a_crc();
- Add a PRINT_HEX macro for driver debugging (replaces print_hex function from bitutils.c);
- Move bit-mirroring related functions to libnfc/mirror-subr.[hc];
- Move iso14443 related functions to libnfc/iso14443-subr.c;
- Move libnfc/bitutils.c hex-dumping code to examples/nfc-utils.c;
- Replace calls to swap_endian32() and swap_endian64() functions with calls to bswap32() and bswap64 provided by endian.h.
And while I am here:
- Fix the DBG macro so that it does not throw warning at compile time.
