/// This file defines two macro asserts.
#include <cassert>
/// This macro asserts that 'a' evaluates to true. In debug mode, this macro
/// will crash the program if the assertion evaluates to false. It (typically)
/// has no effect in release mode.
#define PP_DCHECK(a) assert(a)
/// This macro asserts false in debug builds. It's used in code paths that you
/// don't expect to execute.
/// <strong>Example:</strong>
/// @code
/// if (!pointer) {
/// // Pointer wasn't valid! This shouldn't happen.
/// return;
/// }
/// // Do stuff to the pointer, since you know it's valid.
/// pointer->DoSomething();
/// @endcode
