问题描述
哪里是存储在存储在程序存储器(其中部分)?
Where is a volatile variable stored in the stored in program memory(in which section) ?
推荐答案挥发性是的类型限定符不是存储类说明,所以也没有确定的存储位置在所有;它影响变量的类型,而不是它的存储的定义中。
volatile is a type qualifier not a storage class specifier, so it does not determine storage location at all; it affects the definition of a variable's type, not its storage.
它只是强制编译器明确地读一个变量,其的键入的是挥发性从变量的存储位置(可以是任何地方),而不是假设一些previously在例如寄存器读取值仍然有效。
It simply forces the compiler to explicitly read a variable whose type is volatile from the variable's storage location (wherever that may be) rather than assuming that some previously read value in a register for example remains valid.
