      nfc-emulate-forum-tag4: fix TOCTOU · 679897d0
      Philippe Teuwen authored
      Hopefully fix TOCTOU by calling fopen() before stat()
      
      At least this should prevent Coverity to complain about it:
      CID 1090346 (#1 of 1): Time of check time of use (TOCTOU)
        fs_check_call: Calling function "stat(char const *, struct stat *)" to perform check on "filename".
        toctou: Calling function "fopen(char const * restrict, char const * restrict)" that uses "filename" after a check function. This can cause a time-of-check, time-of-use race condition.
      
      Note that it seems pretty hard to avoid completely:

      nfc-read-forum-tag3: remove redundant error · feb5f37a
      Philippe Teuwen authored
      switch case was redundant as getopt was already telling the issue:
      
        nfc-read-forum-tag3: option requires an argument -- 'o'
        Option -o requires an argument.
      
      This fixes also a problem reported by Coverity about missing break:
      
      CID 1090330 (#1 of 1): Missing break in switch (MISSING_BREAK)
        unterminated_case: This case (value 63) is not terminated by a 'break' statement.

      Calling "nfc_exit(nfc_context *)" dereferences freed pointer "context".

      - Fixed the suppression of the auto-fixup for linking against MS built libs
      - Fixed all the formatting warnings by shifting to inttypes.h specifiers
      - shifted to %lu for DWORD printf

      Convert by value passing of nfc_target to pointer for str_nfc_target and... · c72846e3
      Alex Lian authored
      Convert by value passing of nfc_target to pointer for str_nfc_target and nfc_initiator_target_is_present
      
      This becomes more consistent with all other pass by pointer of most structures.
      Additionally, this should lessen stack memory usage, as building strings with str_nfc_target would push the target (283 bytes) plus then a copy of the info objects (up to 275) onto the stack as it dives into the sprintf functions.
      
      Lastly, this makes my attempt at a .NET wrapper easier, as I can make passing by pointer work, but passing by value seems to bomb on the interop right now.
