What is the significance of volatile keyword?
Volatile keyword is used to inform the compiler not to predict/assume/believe/presume the value of the particular variable which has been declared as volatile.
Why/When do we need volatile ?
In following case we need to use volatile variable.
Memory-mapped peripheral registers
Global variables modified by an interrupt service routine
Global variables within a multi-threaded application
If we do not use volatile qualifier the following problems may arise:
Code that works fine-until you turn optimization on
Code that works fine-as long as interrupts are disabled
Flaky hardware drivers
Tasks that work fine in isolation-yet crash when another task is enabled
