[avr-gcc-list] Getting all 17bits of an objects address ?

[Anton Erasmus]

Hi,

Does anyone have a macro or some other way of getting the full 17bits
of a array defined in program memory ?

if one has:

unsigned char foo[] PROGMEM ={1,2,4};

then the normal C:

unsigned char *ptr=foo; 

only gives the bottom 16bits of the address. I
need to be able to decide at run-time whether an
array is in the top 64K or bottom 64K of program
memory.
