E.7. The volatile Type Qualifier

The volatile type qualifier is applied to a definition of a variable that may be altered from outside the program (i.e., the variable is not completely under the control of the program). Thus, the compiler cannot perform optimizations (such as speeding program execution or reducing memory consumption, for example) that depend on "knowing that a variable's behavior is influenced only by program activities the compiler can observe."
