APPENDBIN

#define APPENDBIN   "ab"

ARRAY_LAST_ENTRY

#define ARRAY_LAST_ENTRY

(

arr

)

(arr)[ARRAY_SIZE(arr) - 1]

Get last array entry

This should be called with a real array. Calling this with a pointer is an error.

ARRAY_SIZE

#define ARRAY_SIZE

(

arr

)

Value:

  ((sizeof(arr)/sizeof((arr)[0])) \
   / ((size_t)(!(sizeof(arr) % sizeof((arr)[0])))))

Calculate the length of a C array

This should be called with a real array. Calling this with a pointer is an error. A mechanism to detect many (though not all) of those errors at compile time is implemented. It works by the second division producing a division by zero in those cases (-Wdiv-by-zero in GCC).
