The

|
|
\fBzip_fopen_encrypted\fR()
|
||
|
|
function opens the encrypted file name
|
||
|
|
\fIfname\fR
|

in

\fIarchive\fR
|

|
|
using the password given in the
|
||
|
|
\fIpassword\fR
|
||
|
|
argument.
|
||
|
|
The
|

\fIflags\fR
|

argument are the same as for

you only need to call them if you want to specify a non-default password

zip_set_default_password(3)).

Upon successful completion, a

|
pointer is returned.
|
||
|
|
Otherwise,
|
||
|
|
\fRNULL\fR
|
||
|
|
is returned and the error code in
|
||
|
|
\fIarchive\fR
|

is set to indicate the error.
