Re: Passing a String to a C/C++ Subprogram (Special Case)

[sbelmont700@gmail.com]

If the client might not be in C anyway, I would put the onus on other units to sort it all out.  Even if a non-C client can be written to figure out a C string, who says the client language can be exported as C convention?  Better to isolate it entirely for when they inevitably change their minds.

generic
   type Client_String_Type is private;
   with function Convert_To_Client(x : String) return Client_String_Type;
   with procedure External_Prog (y : in Client_String_Type);
...

begin 
   ...
   External_Prog (Convert_To_Client("Hello World!"));
   ...
