34 <PRE>To extract from a Password structure (assuming the source password buffer
35 is declared as
"Password source_password
"):
37 char password_buffer[PASSMAX];
39 memcpy(password_buffer, source_password.password, PASSMAX);
40 cipher = strdup(source_password.cipher);
42 To copy into a Password structure (assuming the target password buffer is
43 declared as
"Password target_password
" and the data to be copied is in
44 "password_buffer
" and
"cipher
" variables as above):
46 Password temp_password;
47 init_password(
&temp_password);
48 memcpy(temp_password.password, password_buffer, PASSMAX);
49 temp_password.cipher = cipher;
50 copy_password(
&target_password,
&temp_password);
51 // Don't leave a copy of the password in memory
52 memset(
&temp_password,
0, sizeof(temp_password));
53 memset(password_buffer,
0, PASSMAX);
55 I actually think I'll add a set_password() function to simplify this, so
56 the above would then become simply:
58 set_password(
&target_password, password_buffer, cipher);
59 // Don't leave a copy of the password in memory
60 memset(password_buffer,
0, PASSMAX);

96 </I>>>><i> Hy,
98 </I>>>><i> I'm migrating my old modules for ircservices-
5.1.11, but I've seen that
99 </I>>>><i> there were many changes in the nickgroupinfo_ struct.
100 </I>>>><i> "char pass[PASSMAX];
" were replaced by
"Password pass;
", so my module
101 </I>>>><i> won't compile anymore:
103 </I>>>><i> modules/nickserv/dbsynch.c: In function `copy_data':
104 </I>>>><i> modules/nickserv/dbsynch.c:
83: error: incompatible type for argument
1
105 </I>>>><i> of `__builtin_strncpy'
108 </I>>>><i> Line of this code:
110 </I>>>><i> static void copy_data(MYSQL_ROW row, unsigned long *lengths, NickInfo
111 </I>>>><i> *ni, NickGroupInfo *ngi) {
112 </I>>>><i> char temp[
100];
113 </I>>>><i> strncpy(ngi-
>pass, row[field(MYSQL_FIELD_USERINFO_PASSWORD)], PASSMAX
<
114 </I>>>><i> lengths[field(MYSQL_FIELD_USERINFO_PASSWORD)] ? PASSMAX :
115 </I>>>><i> lengths[field(MYSQL_FIELD_USERINFO_PASSWORD)] +
1);
116 </I>>>><i> ....
118 </I>>>><i> When I replace
"ngi-
>pass
" by
"&ngi-
>pass
" there's only a warning left,
119 </I>>>><i> but by running this function copy_data my services crashes.
121 </I>>>><i> Any Ideas?
122 </I>>>><i> Regards.
