Question

I have declared my array like this:

FT_Interface<4096> *to_make_ft[3] = { /* initialization with existing objects */ };

my interface is declared like this:

template<cyg_ucount32 S, int N>
class FT_Thread {
  FT_Thread(FT_Interface<S> *entry[N]){}
};

And i call it (as expected with):

FT_Thread<4096, 3> ft(to_make_ft);

Yet it complains that the pointer has decayed.

ecos/install/include/ft/thread.hxx:70: error: incompatible types in assignment of ‘FT_Interface<4096u>**’ to ‘FT_Interface<4096u>* [3]’

Is there any way to prevent this from happening?

Answer 1

You need

FT_Thread(FT_Interface<S>* (&entry)[N]){}
//             note these  ^^-----^

With that, you get a reference to the array.

Edit: Of course, if you want a pointer to the array, you can have just that:

FT_Thread(FT_Interface<S>* (*entry)[N]){}

Though you need to call it with FT_Thread<4096,3> ft(&to_make_ft).
