Hello, I am delcaring some memory specific pointers using the examples on page 76 of the C51 Compiler Users Guide 01.97.
unsigned char xdata * idata key
warning C258: 'key' mspace on parameter ignored
Thanks Bob, I have just read that section now and it has cleared up a few other confusions for me. I think I have solved my original problem, as the warnings were generated when the pointer declaration was a parameter in a function declaration. Of course I shouldn't have specified the memory type of the pointer in the function declaration, just the memory type of what is being pointed to. Thanks again, Nick
