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
archive specifies the zip archive to which the file
should be added. name is the file's name in the zip
archive (for zip_file_add()), while
index specifies which file should be replaced (for
zip_file_replace()). The flags
argument can be any combination of ZIP_FL_OVERWRITE
with one of ZIP_FL_ENC_*:
ZIP_FL_OVERWRITEzip_file_add only.ZIP_FL_ENC_GUESSZIP_FL_ENC_UTF_8ZIP_FL_ENC_CP437NOTE:
zip_source_free(3) should not
be called on a source after it was used successfully
in a zip_file_add or
zip_file_replace call.
Please also note that when using
zip_replace, 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 zip_replace with
zip_file_extra_field_set(3).
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 archive is set to
indicate the error.
