I was just wondering if someone could explain the meani开发者_运维问答ng of this: Operations like increment and
Okay, suppose I have a bunch of variables, one of them declared volatile: int a; int b; int c; volatile int v;
In my main coroutine, I am removing or adding entries from a table depending on user operations. In the background, I\'d like to iter开发者_如何学Cate over the entries in the table. I don\'t mind part
Currently I can\'t understand when we should use volatile to declare variable. I have do some study and searched some materials about it for a long time and know that when a field is declared volatil
I am trying to create an example to display the difference between volatile and usual variables like:
When writing C programs that need to share a file scope variable between the application and an interrupt routine/a thread/a callback routine, it is well-known that the variable must be declared volat
If I have a C++ method declaration as follows: class A { public: double getPrice() volatile; }; What does volatile represent here?
If i declare a variable as volatile and if I do开发者_如何学Pythonnt use it any where in the program, will the compiler optimize that variable ?
I want to make my class thread-safe without large overhead. The instances will be seldom used concurrently, but it may happen.
