In these rare -// cases, you have to use the unsafe ARRAYSIZE() macro below. This is -// due to a limitation in C++'s template system.

It's less safe than arraysize as it accepts some -// (although not all) pointers. Therefore, you should use arraysize -// whenever possible. -// -// The expression ARRAYSIZE(a) is a compile-time constant of type -// size_t. -// -// ARRAYSIZE catches a few type errors. If you see a compiler error -// -// "warning: division by zero in ..." -// -// when using ARRAYSIZE, you are (wrongfully) giving it a pointer. -// You should only use ARRAYSIZE on statically allocated arrays. -// -// The following comments are on the implementation details, and can -// be ignored by the users. -// -// ARRAYSIZE(arr) works by inspecting sizeof(arr) (the # of bytes in -// the array) and sizeof(*(arr)) (the # of bytes in one array -// element). If the former is divisible by the latter, perhaps arr is -// indeed an array, in which case the division result is the # of -// elements in the array. Otherwise, arr cannot possibly be an array, -// and we generate a compiler error to prevent the code from -// compiling. -// -// Since the size of bool is implementation-defined, we need to cast -// !(sizeof(a) & sizeof(*(a))) to size_t in order to ensure the final -// result has type size_t. -// -// This macro is not perfect as it wrongfully accepts certain -// pointers, namely where the pointer size is divisible by the pointee -// size. Since all our code has to go through a 32-bit compiler, -// where a pointer is 4 bytes, this means all pointers to a type whose -// size is 3 or greater than 4 will be (righteously) rejected. -// -// Kudos to Jorg Brown for this simple and elegant implementation. -// -// - wan 2005-11-16 -// -// Starting with Visual C++ 2005, WinNT.h includes ARRAYSIZE.
