hi, can u tell me what is the meaning of this code? volatile BOOL GotSUD;

[khatereh]

what is the meaning of this code
volatile BOOL GotSUD;
BOOL Rwuen;
BOOL Selfpwr;

[Meetee]

Code declares three variables with BOOL datatype. For data types please refer this

volatile keyword indicates that GotSUD variable can be modified by a process which is outside the control of the compiler.

Are you asking the same thing, right?

Adding to what zodilla58 said:

volatile means that the variable may be altered by means not in control of the compiler. Therefore, this is an instruction to your compiler to not make assumptions about this variable - like put it in a register or some other optimization. The compiler is to create an actual memory variable for this value.

Finally (just to be clear), those three lines don't do anything. They define variables, but there is no executable code in that snippet.
