Re: C lib returns char** - How in ADA?

Hi, 

I mistakenly hit the send before finishing ...

Have a look at package Interfaces.C.Strings in the
references manual. The package provides :

type char_array_access is access all char_array;
type chars_ptr is private;
type chars_ptr_array is array (size_t range <>) of chars_ptr;

which appears to be what you are looking for.

Then look at Interfaces.C.Pointers.

It gets tricky since you are importing a non-Ada object, but

    package IC  renames Interfaces.C;
    package ICS renames Interfaces.C.Strings;
    package ICP is new Interfaces.C.Pointers (
        Index => IC.Size_t,
        Element => ICS.Chars_Ptr,
        Element_Array => ICS.Chars_Ptr_Array,
        Default_Terminator => ???????
    );

Cannot remember what <???????> should be,

   ICP.Copy_Terminated_Array (...)

should get the foreign data structure into your
application.

Its been a while since I played with this, so details
are fuzzy .. except that I quickly found a hack to
replace the way you are supposed to do it described 
above :-)
