C++ needs casts in order to assign a void* to another pointer type.
As typeof operator is a gcc extension, we define EINA_TYPEOF(x) as
"typeof" on gcc with c++ source and as nothing otherwise.
Lucas, as I told you, I'd rather use the following patch, but it would
not help other C++ compilers, so not a real solution.
What about this:
template <typename T>
inline T *cast_to(T *, void *p)
{
return (T *)p;
}
...
data = cast_to(data, l);
I haven't used c++ since a while, but I think this should be portable.
They have the fancy templates dynamic_cast<type>(ptr) and
static_cast<type>(ptr)
Yes, I know. But I wasn't sure which one to chose, so I took a normal C
cast as the OP did.
static_cast is better that dynamic_cast in that case (imho)
Yes, static_cast is the most common cast operator and replaces the C-style
casts.
the C-style cast is reinterpret_cast, which should be avoided if possibe
in C++.
Vincent
dynamic_cast will not work as it checks dynamically for the hierarchy
class of both pointers. You should only use that with with polymorphic
classes.
