.SH "LIBRARY"
libzip (-lzip)
.SH "SYNOPSIS"
#include <zip.h>
.PP

.SH "DESCRIPTION"
The function
zip_file_add
adds a file to a zip archive, while
zip_file_replace
replaces an existing file in a zip archive.
The argument
\fBarchive\fR
specifies the zip archive to which the file should be added.
\fBname\fR
is the file's name in the zip archive (for
zip_file_add ),
while
\fBindex\fR
specifies which file should be replaced (for
zip_file_replace ).
The
\fBflags\fR
argument can be any combination of
\fBZIP_FL_OVERWRITE\fR
with one of
\fBZIP_FL_ENC_* :\fR
.RS
.TP 22
\fBZIP_FL_OVERWRITE\fR
Overwrite any existing file of the same name.
For
.Nm zip_file_add
only.
.TP 22
\fBZIP_FL_ENC_GUESS\fR
Guess encoding of
\fBname\fR
(default).
.TP 22
\fBZIP_FL_ENC_UTF_8\fR
Interpret
\fBname\fR
as UTF-8.
.TP 22
\fBZIP_FL_ENC_CP437\fR
Interpret
\fBname\fR
as code page 437 (CP-437).
.RE
The data is obtained from the
\fBsource\fR
argument.
See the
zip_source_*
functions cited in
SEE ALSO.
.SH "RETURN VALUES"
Upon successful completion,
zip_file_add
returns the index of the new file in the archive, and
zip_file_replace
returns 0.
Otherwise, \-1 is returned and the error code in
\fBarchive\fR
is set to indicate the error.
.SH "EXAMPLES"
.Bd \-literal \-offset indent
struct zip_source *s;
const char buf="teststring";

if ((s=zip_source_buffer(archive, buffer, sizeof(buf), 0)) == NULL ||
    zip_file_add(archive, name, s, ZIP_FL_ENC_UTF_8) \*[Lt] 0) {
    zip_source_free(s);
    printf("error adding file: %s\en", zip_strerror(archive));
}

and
zip_file_replace

is not provided).
