.SH "DESCRIPTION"
The
\fBzip_get_name\fR()
function returns the name of the file at position
\fIindex\fR
in
\fIarchive\fR.
The name is in UTF-8 encoding unless
\fRZIP_FL_ENC_RAW\fR
was specified (see below).
.PP
If
\fIflags\fR
is set to
\fRZIP_FL_UNCHANGED\fR,
the original unchanged filename is returned.
The returned string must not be modified or freed, and becomes invalid when
\fIarchive\fR
is closed.
.PP
Additionally, the following
\fIflags\fR
are supported:
.RS 6n
.TP 21n
\fRZIP_FL_ENC_RAW\fR
Return the unmodified names as it is in the ZIP archive.
.TP 21n
\fRZIP_FL_ENC_GUESS\fR
(Default.)
Guess the encoding of the name in the ZIP archive and convert it
to UTF-8, if necessary.
(Only CP-437 and UTF-8 are recognized.)
.TP 21n
\fRZIP_FL_ENC_STRICT\fR
Follow the ZIP specification and expect CP-437 encoded names in
the ZIP archive (except if they are explicitly marked as UTF-8).
Convert it to UTF-8.
.RE
\fINote\fR:
ASCII is a subset of both CP-437 and UTF-8.
.SH "RETURN VALUES"
Upon successful completion, a pointer to the name is returned.
Otherwise,
\fRNULL\fR
and the error code in
\fIarchive\fR
is set to indicate the error.
.SH "ERRORS"
\fBzip_get_name\fR()
fails if:
.TP 19n
[\fRZIP_ER_DELETED\fR]
\fIindex\fR
refers to a file that has been deleted
(see
zip_delete(3)).
.TP 19n
[\fRZIP_ER_INVAL\fR]
\fIindex\fR
is not a valid file index in
\fIarchive\fR,
or
\fIindex\fR
points to an added file and
\fRZIP_FL_UNCHANGED\fR
is set.
.TP 19n
[\fRZIP_ER_MEMORY\fR]
Required memory could not be allocated.

was changed from
\fIint\fR
to
\fIzip_uint64_t\fR.
In libzip 0.11 the type of
\fIflags\fR
was changed from
\fIint\fR
to
