Hello,
In c++, suppose I define a template class
typedef unsigned long tWord32;
...
template<class T, tWord32 size>
class cBuffer
{
public:
T mBuff[size];
};
then declare a global,
cBuffer<tWord32, 512> longBuff;
Is &(longBuff.mBuff) known at link-time?
Yes.

Now suppose I did this,
template<class T, tWord32 size>
class cBuffer
{
public:
T * Address()
{ return &mBuff; };
private:
T mBuff[size];
};
cBuffer<tWord32, 512> longBuff;
tWord32 * ptr = longBuff.Address();
Is the result of the inline method invocation expression
"longBuff.Address()" a push statement that gets executed during global
object initialization or is it treated as a field access expression and
resolved at compile-time?
I am pretty sure that it is executed at run-time during global object
initialization. However, to be sure I would just write a small test
program, compile it and check the resulting assembly code with objdump.
