Re: [GD-General] Offset a void pointer

[Richard F. <ra...@gm...>]

if you are referring to this:

http://gcc.gnu.org/gcc-3.4/changes.html
from the section starting:
"The cast-as-lvalue extension has been removed for C++ and deprecated
for C and Objective-C. In particular, code like this: "

then that is just that GCC has caught up with MS compilers in
dissallowing the implicit lvalue return of standard C style casts

Still appears to be perfectly legal to cast to an explicit lvalue type...

Please correct me if i am wrong on this... At least in my head it
certainly seems to make no sense to take out casting to a modifiable
type...

Regarding Ola Olsson: static_cast is a little bit safer, as the types
Cavey Gerard was referring to were reasonably compatible. AFAIK
reinterpret_cast is used to allow you to do more "dodgy" casting, e.g.
between a function pointer and a float, something which static_cast
does not do...
Again, please correct me if i am wrong.
