#95204 - const Responding to: ???'s previous message |
In other compilers const can refer to the memory space as well (code in Keil), so you can have a const pointer (a pointer that cannot point to any other address) pointing to const data (can't modify the data). Some compilers use the latter to indicate ROM space.
Dan Saks has a ton of fun stuff like that at ESP mag: http://embedded.com/showArtic...ID=9900041 (Caveat: That particular article is more about C++ and references than C pointers, but it's a "fun" read). Google Saks, const, ROM and the like for more interesting reads... GB |
