pointer to const value(指向常量的指针), 不能用于改变其所指对象的值。要想存放常量对象的地址,只能使用指向常量的指针。 low-level const, pointer can be changed but not variable it pointed. const double pi = 3.14; const double *ptr = π ///< 意为解引用ptr (*ptr) 会得到一个const double的...
常量指针(const pointer)必须初始化,而且一旦初始化完成,则它的值(也就是存放在指针中的那个地址)就不能再改变了。 int errNumb = 0; int *const curErr = &errNumb; 也可以定义一个指向常量的常量指针(const pointer to const)。 const double pi=3.14; const double * const pip = π 为了判断...

So the value we read was in the buffer and read correctly, it was just never checked against the bounds. The correct fix seems to be to add index bounds check somewhere, no idea where that should be though. turolassignedturolandkimkullingand unassignedturolJan 24, 2018 ...
