I need to pass it converted to a C string into a C library function. Now I do it with Interfaces.C.Strings.New_String. But it is slow as it uses the heap and requires (not to forget incidentally!) further Interfaces.C.Strings.Free. Is there a better way to do this? I mean that we would probably create a nul-terminated char_array (not on the heap but on the stack!) and pass the pointer to its first element. This would be both safer an faster. Can you elaborate on this? -- Victor Porton - http://portonvictor.org
