.Sh SYNOPSIS
.In zip.h
.Ft zip_int64_t
.Fn zip_file_add "zip_t *archive" "const char *name" "zip_source_t *source" "zip_flags_t flags"
.Ft int
.Fn zip_file_replace "zip_t *archive" "zip_uint64_t index" "zip_source_t *source" "zip_flags_t flags"
.Sh DESCRIPTION
The function
.Fn zip_file_add
adds a file to a zip archive, while
.Fn zip_file_replace
replaces an existing file in a zip archive.
The argument
.Ar archive
specifies the zip archive to which the file should be added.
.Ar name
is the file's name in the zip archive (for
.Fn zip_file_add ) ,
while
.Ar index
specifies which file should be replaced (for
.Fn zip_file_replace ) .
The
.Ar flags
argument can be any combination of
.Dv ZIP_FL_OVERWRITE
with one of
.Dv ZIP_FL_ENC_* :
.Bl -tag -width XZIPXFLXENCXSTRICTXX
.It Dv ZIP_FL_OVERWRITE
Overwrite any existing file of the same name.
For
.Nm zip_file_add

.Em NOTE :
.Xr zip_source_free 3
should not be called on a
.Ar source
after it was used successfully in a

or
.Nm zip_file_replace
call.
.Sh RETURN VALUES
Upon successful completion,
.Fn zip_file_add
returns the index of the new file in the archive, and
.Fn zip_file_replace
returns 0.
Otherwise, \-1 is returned and the error code in
.Ar archive
is set to indicate the error.

.Bd -literal -offset indent
zip_source_t *s;
const char buf[]="teststring";
if ((s=zip_source_buffer(archive, buf, sizeof(buf), 0)) == NULL ||
zip_file_add(archive, name, s, ZIP_FL_ENC_UTF_8) < 0) {
zip_source_free(s);
printf("error adding file: %s\en", zip_strerror(archive));
}
