General C question - volatile cast

Posted on November 30, 2015 at 19:31

Hello,

Using a lot of global variables modified into ISR sections, I use a lot the ''volatile'' keyword when needed.

volatile int foo;

int square(int din)

{

   return din*din;

}

result = square(foo); // Does not compile: cast error

Actually, this kind of C-code are not supported by IAR:

''int'' type is not compatible with ''volatile int'' type.

The obvious solution is to do a cast:

result = square((int)foo); // Compile very well but absolutely boring!

With big projects, many structures and many functions with many parameters doing a cast for each parameter is very time-consuming and does not render the code very clear.

Is there a way to tell to the compiler: ''Don't annoy me with volatile uncasted types!'' ?

Thank you
