Isn't it a problem that with true C++ functions it is possible that
functions
can exist with the same name but different parameters, for example
void FOO (int x);
void FOO (double x);
void FOO (char *x);
and C++ chooses the right one depending on the parameter used on the
function call?
This is done by a mechanism known as "name mangling" (that is,
a designation of the parameter type is appended to the function name,
giving the true "technical" function name).
So, if this is true, how would you implement such a C++ function in
ASSEMBLER,
if you don't declare it as extern "C" or extern "ASSEMBLER"?
This being said: I don't think, the default mechanism will work in this
case,
but I may be wrong with this.
Kind regards

I'm pretty sure I know the answer to this question but wondered if someone
knew for sure.
If I declare a function void FOO(int x = 1); and call it with FOO() then the
construction and passing of an integer parameter with a value of 1 is
entirely handled by the calling module, correct?
The reason I am asking ... suppose FOO is a function implemented in
assembler, not in C++. The declaration of the default parameter and the
invocation with the parameter omitted will still work, right?
