.PD
.SH "DESCRIPTION"
The function
\fBzip_file_add\fR()
adds a file to a zip archive, while
\fBzip_file_replace\fR()
replaces an existing file in a zip archive.
The argument
\fIarchive\fR
specifies the zip archive to which the file should be added.
\fIname\fR
is the file's name in the zip archive (for
\fBzip_file_add\fR()),
while
\fIindex\fR
specifies which file should be replaced (for
\fBzip_file_replace\fR()).
The
\fIflags\fR
argument can be any combination of
\fRZIP_FL_OVERWRITE\fR
with one of
\fRZIP_FL_ENC_*\fR:
.TP 22n
\fRZIP_FL_OVERWRITE\fR
Overwrite any existing file of the same name.
For
\fBzip_file_add\fR
only.
.TP 22n
\fRZIP_FL_ENC_GUESS\fR
Guess encoding of
\fIname\fR
(default).
(Only CP-437 and UTF-8 are recognized.)
.TP 22n
\fRZIP_FL_ENC_UTF_8\fR
Interpret
\fIname\fR
as UTF-8.
.TP 22n
\fRZIP_FL_ENC_CP437\fR
Interpret
\fIname\fR
as code page 437 (CP-437).
.PD 0
.PP
The data is obtained from the
\fIsource\fR
argument, see
zip_source(3).
.PD
.PP
\fINOTE\fR:
zip_source_free(3)
should not be called on a
\fIsource\fR
after it was used successfully in a
\fBzip_file_add\fR
or
\fBzip_file_replace\fR
call.
.PP
Please also note that when using
\fBzip_replace\fR,
the target file's extra field information will be deleted since this
usually is dependent on the file contents.
If you want to keep them, query them beforehand with
zip_file_extra_field_get(3)
and restore them after
\fBzip_replace\fR
with
zip_file_extra_field_set(3).
.SH "RETURN VALUES"
Upon successful completion,
\fBzip_file_add\fR()
returns the index of the new file in the archive, and
\fBzip_file_replace\fR()
returns 0.
Otherwise, \-1 is returned and the error code in
\fIarchive\fR
is set to indicate the error.
.SH "EXAMPLES"

.SH "ERRORS"
\fBzip_file_add\fR()
and
\fBzip_file_replace\fR()
fail if:
.TP 19n
[\fRZIP_ER_EXISTS\fR]
There is already a file called
\fIname\fR
in the archive.
(Only applies to
\fBzip_file_add\fR(),
and only if
\fRZIP_FL_OVERWRITE\fR
is not provided).
.TP 19n
[\fRZIP_ER_INVAL\fR]
\fIsource\fR
or
\fIname\fR
are
\fRNULL\fR,
or
\fIindex\fR
is invalid.
.TP 19n
[\fRZIP_ER_MEMORY\fR]
Required memory could not be allocated.
.TP 19n
