// This file defines the arraysize() macro and is derived from Chromium's // base/macros.h.
// The arraysize(arr) macro returns the # of elements in an array arr. // The expression is a compile-time constant, and therefore can be // used in defining new arrays, for example. If you use arraysize on // a pointer by mistake, you will get a compile-time error.
// This template function declaration is used in defining arraysize. // Note that the function doesn't need an implementation, as we only // use its type. template <typename T, size_t N> char (&ArraySizeHelper(T (&array)[N]))[N];
