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

>I'm migrating my old modules for ircservices-5.1.11, but I've seen that 
>there were many changes in the nickgroupinfo_ struct.
>"char pass[PASSMAX];" were replaced by "Password pass;", so my module 
>won't compile anymore:
>modules/nickserv/dbsynch.c: In function `copy_data':
>modules/nickserv/dbsynch.c:83: error: incompatible type for argument 1 
>of `__builtin_strncpy'
>Line of this code:
>static void copy_data(MYSQL_ROW row, unsigned long *lengths, NickInfo 
>*ni, NickGroupInfo *ngi) {
>        char temp[100];
>strncpy(ngi->pass, row[field(MYSQL_FIELD_USERINFO_PASSWORD)], PASSMAX < 
>lengths[field(MYSQL_FIELD_USERINFO_PASSWORD)] + 1);
>When I replace "ngi->pass" by "&ngi->pass" there's only a warning left, 
>but by running this function copy_data my services crashes.
