I have a function whose argument consist of a pointer to unsigned char.

Now, I want to pass an array of type volatile unsigned char. :!:

If I try to pass it directly, compiler doesn't allow me to do so. I think it needs typecasting to be done but I am not sure if it works. :sad:

I am searching about it on the google as well.

Can anyone here tell me what can be the probable way to do this?
 

assuming you have
Code: 
volatile unsigned char x[10]={'Z'};
and a function
Code: 
void test(unsigned char *ch)
you can try
Code: 
    test((unsigned char *) x);
 
That is working.

I initially tried it in reverse way by which, normal pointer was casted to volatile pointer. that is why I did get an error
