How to define a macro describing a memory location? [closed]

Answer 1

Something like this should do the trick:

#define WRITE_TO_0X10000(v) (*((char *)0x10000) = (char)(v))

You didn't defined what kind of value should be written, I supposed that a byte is to be written. The macro does the following :

1. convert the value 0x10000 to a pointer to char ((char *)0x10000)
2. force the value to be a char (8-bits) ((char)(v))
3. write the value to the memory pointed *pointer = value

Another possibility is:

#define POINTER_TO_0x10000 ((char *)0x10000)
*POINTER_TO_0X10000 = some_char_value

You can easily adapt to any other type you need.
