Detailed Description

This file defines two macro asserts.

Define Documentation

#define PP_DCHECK ( a ) assert(a)

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_NOTREACHED ( ) assert(false)

This macro asserts false in debug builds.

It's used in code paths that you don't expect to execute.

Example:

 if (!pointer) {
 // Pointer wasn't valid! This shouldn't happen.
 PP_NOTREACHED();
 return;
 }
 // Do stuff to the pointer, since you know it's valid.
 pointer->DoSomething();
