  34 <PRE>Passwords are no longer stored as simple strings, since each password
  35 can be encrypted with a different method (cipher).  To save data from
  36 a Password structure, you need to save both the contents of
  37 Password.password (as a binary buffer, not a string) and the string
  38 pointed to by Password.cipher (which may be NULL).  To restore a
  39 Password structure, fill in the password and cipher fields in a
  40 temporary variable, then use copy_password() to copy the data to the
  41 destination Password structure.

  47 &gt;<i>Hy,
  48 </I>&gt;<i>
  49 </I>&gt;<i>I'm migrating my old modules for ircservices-5.1.11, but I've seen that
  50 </I>&gt;<i>there were many changes in the nickgroupinfo_ struct.
  51 </I>&gt;<i>&quot;char pass[PASSMAX];&quot; were replaced by &quot;Password pass;&quot;, so my module
  52 </I>&gt;<i>won't compile anymore:
  53 </I>&gt;<i>
  54 </I>&gt;<i>modules/nickserv/dbsynch.c: In function `copy_data':
  55 </I>&gt;<i>modules/nickserv/dbsynch.c:83: error: incompatible type for argument 1
  56 </I>&gt;<i>of `__builtin_strncpy'
  57 </I>&gt;<i>
  58 </I>&gt;<i>
  59 </I>&gt;<i>Line of this code:
  60 </I>&gt;<i>
  61 </I>&gt;<i>static void copy_data(MYSQL_ROW row, unsigned long *lengths, NickInfo
  62 </I>&gt;<i>*ni, NickGroupInfo *ngi) {
  63 </I>&gt;<i>        char temp[100];
  64 </I>&gt;<i>strncpy(ngi-&gt;pass, row[field(MYSQL_FIELD_USERINFO_PASSWORD)], PASSMAX &lt;
  65 </I>&gt;<i>lengths[field(MYSQL_FIELD_USERINFO_PASSWORD)] ? PASSMAX :
  66 </I>&gt;<i>lengths[field(MYSQL_FIELD_USERINFO_PASSWORD)] + 1);
  67 </I>&gt;<i>....
  68 </I>&gt;<i>
  69 </I>&gt;<i>When I replace &quot;ngi-&gt;pass&quot; by &quot;&amp;ngi-&gt;pass&quot; there's only a warning left,
  70 </I>&gt;<i>but by running this function copy_data my services crashes.
  71 </I>&gt;<i>
  72 </I>&gt;<i>Any Ideas?
  73 </I>&gt;<i>Regards.
