在C++memory model中对static local variable,说道:The initialization of such a variable is defined to occur the first time control passes through its declaration; for multiple threads calling the function, this means there’s the potential for a race condition to define first. 局部静态变量不仅只会...

Define variable(s) in header file referenced by multiple c files. (CH:在 被多个c文件引用 的 头文件中定义变量) If the variable is initialized, GCC will report an error. (CH:如果这个变量被初始化, GCC会报错) 一般来说,如果需要,变量的声明一边放到头文件中,变量的...
假如声明此变量时不加static,则编译器会为它创建一个“外部符号”(external symbol)。此时若是另一个编译单元中也声明了同名变量,那么编译器就抛出一条错误消息: duplicate symbol _kAnimationDuration in:EOCAnimatedView.o EOCOtherView.o 1. 实际上,如果一个变量既声明为static,又声明为const,那么编译器根本不会...
