I tried to build a class with a private function
`conversation_func` to call it inside the public authentication
function. When compiling I get this message:
```
source/login/auth.d(87,46): Deprecation: casting from extern
(C) int delegate(int num_msg, const(pam_message**) msg,
pam_response** resp, void* appdata_ptr) to extern (C) int
function(int, const(pam_message**), pam_response**, void*)* is
deprecated
```
And when I start up, at the moment of calling the
authentication function, I get `Segmentation fault`.
Is the function identified differently in the class? How can
this be fixed?
Would you try static this?
```d
// 1. Salih changed it:
extern(C) static int conversation_func(int num_msg, const
pam_message **msg, pam_response **resp, void *appdata_ptr)
{ /* ... */}
```
There is no need for `this`.
```d
// 2. Salih changed it:
pam_conv conv = {
cast(conversation*)&/*this.*/conversation_func,
appdata_ptr
};
```
