Re: C binding issue

[David Holm <david@realityrift.com>]

Something like this if I'm not mistaken (been a while since I used callbacks in Ada):

type size_t_ptr is access all Interfaces.C.size_t;
type Lua_Chunkreader_Proc is access function
   (L : Lua_State_Type; Ptr : System.Address; Sz : size_t_ptr) return
   Interfaces.C.Strings.chars_ptr;
