Hello,

I'm still working on mapping libpam in Linux using jna. I think once I get an understanding of the first couple of functions it won't be too bad. Anyhow here are the declarations of the first two functions I am trying to map:

int pam_start(const char *service_name, const char *user, const struct pam_conv *pam_conversation, pam_handle_t **pamh); int pam_end(pam_handle_t *pamh, int pam_status);

and here are the related c structs:

struct pam_message { int msg_style; const char *msg; };

struct pam_response { char *resp; int resp_retcode; };

struct pam_conv { int (*conv)(int num_msg, const struct pam_message **msg, struct pam_response **resp, void *appdata_ptr); void *appdata_ptr; };

Here is what I've come up with so far. I would appreciate it if someone could tell me whether or not what I have come up with so far will work.

public class PamMessage extends Structure { int msgStyle; String msg; }

public class PamResponse extends Structure { public String resp; public int respRetCode; }

public class PamConv extends Structure { public static interface Conv extends Callback { int callback(int numMsg, PamMessage pamMessage, PamResponse resp, Pointer appDataPtr); }

Conv conv; Pointer appDataPtr; }

public interface LibPam extends Library { public int pam_start(String service_name, String user, PamConv pam_conversation, PointerByReference pamh);

public int pam_end(Pointer pamh, int pam_status); }
