In this case, you have to call the specific imap functions.

2/ generic usage

if you wish to use the generic mailsession functions, you have to connect=
,
for example with the following code :

int tcp_connect(char * server, uint16_t port)
{
  struct hostent * remotehost;
  struct sockaddr_in sa;
  int s;
  int r;

  s =3D socket(PF_INET, SOCK_STREAM, 0);
  if (s =3D=3D -1)
    return -1;

  remotehost =3D gethostbyname(server);
  if (remotehost =3D=3D NULL)
    return -1;

  sa.sin_family =3D AF_INET;
  sa.sin_port =3D htons(port);
  memcpy(&sa.sin_addr, remotehost->h_addr, remotehost->h_length);

  r =3D connect(s, (struct sockaddr *) &sa, sizeof(struct sockaddr_in));
  if (r =3D=3D -1)
    return -1;

  return s;
}

once you get the socket, you can create a mailstream :

{=20
  mailstream * s;

  s =3D mailstream_socket_open(fd);

  ...
}

mailstream is the data structure to abstract the connection.

{
  ...

  session =3D mailsession_new(imapdriver);

  /* or

     session =3D mailsession_new(imapdriver_cached);

     r =3D mailsession_parameters(session,
         IMAPDRIVER_CACHED_SET_CACHE_DIRECTORY,=20
         directory_name);
    =20
     to take advantage of a local cache
  */

  r =3D mailsession_connect_stream(session, s);

  switch (r) {
  case MAIL_NO_ERROR_AUTHENTICATED:
    break;
  case MAIL_NO_ERROR_NON_AUTHENTICATED:
    break;
  case MAIL_NO_ERROR:
    break;
  default:
    printf("%s\n", maildriver_strerror(r));
    break;
  }

  r =3D mailsession_login(session, folder->auth.user, folder->auth.passwd=
);

  ...
   make calls to generic interface
  ...

  mailsession_logout(session);
  mailsession_free(session);
}
