I think you should, as suggested above, explain what your code should do.
Because you are doing some, in my oppinion, strage things here.
For example this line of code:
(++radioIn >= 2) && (radioIn = 0) ;
doesnt make sense when written as a statement. You will add one to radioIn
and set radioIn to zero while doing a logic and (?).
And one other thing:
for (j=0;j<=9;j++)
{
line_a[j]=radioQueue[radioOut];
}
You are accessing 10 elements in line_a, but it only has 2 elements?
And the final question: why do you want to xor 2 message_t struct pointers.
If everything is correct then I guess casting the pointers to ints as
suggested by Michael would do the job.
