"There is no delight in owning anything unshared."
"A book lying idle on a shelf is wasted ammunition. Like money, books must be kept in constant circulation. Lend and borrow to the maximum -- of both books and money! But especially books, for books represent infinitely more than money. A book is not only a friend, it makes friends for you. When you have possessed a book with mind and spirit, you are enriched. But when you pass it on you are enriched threefold."

[John Rajesh]

A variable should be declared volatile whenever its value can be changed by something beyond the control of the program in which it appears, such as a concurrently executing thread. Volatile, can appear only once in a declaration with any type specifier; however, they cannot appear after the first comma in a multiple item declaration.

 

Keyword volatile can be placed before or after the data type in the variable definition. For example following declaration are identical:

Volatile T a =3;
T volatile a=3; 

The declaration declares and initializes an objet with type volatile T whose value will be always read from memory

Use of volatile

- An object that is a memory-mapped I/O port
- An object variable that is shared between multiple concurrent processes
- An object that is modified by an interrupt service routine
-
