/// Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element /// //# This makes an effort to find cases where the argument to sizeof is wrong //# in memory allocation functions by checking the type of the allocated memory //# when it is a double pointer and ensuring the sizeof argument takes a pointer //# to the the memory being allocated.
