Build-time reference to per-configuration output subdirectory. For native build systems supporting multiple configurations in the build tree (such as Visual Studio Generators and Xcode), the value is a reference to a build-time variable specifying the name of the per-configuration output subdirectory...

void init( int& i ); int f( bool b ) { int i; init(i); if ( b ) { i = 0; } return i; // i is assumed to be initialized because it's passed by reference to init() } 这支持将指向变量的指针传入初始化函数的模式。 这种启发式方法可能会导致漏报,因为许多函数需要指向初始化...
