.SH "DESCRIPTION"
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
zip_fopen(3).
.PP
The
\fBzip_fopen_index_encrypted\fR()
function opens the file at position
\fIindex\fR,
see
zip_fopen_index(3).
These functions are called automatically by
zip_fopen(3);
you only need to call them if you want to specify a non-default password
(see
zip_set_default_password(3)).
.SH "RETURN VALUES"
Upon successful completion, a
\fIstruct zip_file\fR
pointer is returned.
Otherwise,
\fRNULL\fR
is returned and the error code in
\fIarchive\fR
is set to indicate the error.
.SH "ERRORS"
.TP 22n
[\fRZIP_ER_NOPASSWD\fR]
No password was provided.
.PP
The function
\fBzip_fopen_encrypted\fR()
may also fail and set
\fIzip_err\fR
for any of the errors specified for the routine
zip_fopen(3).
.PP
The function
\fBzip_fopen_index_encrypted\fR()
may also fail and set
\fIzip_err\fR
for any of the errors specified for the routine
zip_fopen_index(3).
