The functions
zip_source_zip_file()
and
zip_source_zip_file_create()
create a zip source from a file in a zip archive. The
srcarchive argument is the (open) zip archive
containing the source zip file at index srcidx.
length bytes from offset start
will be used in the zip_source. If length is -1, the
rest of the file, starting from start, is used.
If you intend to copy a file from one archive to another, using
the flag ZIP_FL_COMPRESSED is more efficient, as it
avoids recompressing the file data.
Supported flags are:
ZIP_FL_COMPRESSEDZIP_FL_ENCRYPTEDZIP_FL_COMPRESSED.) This is only supported if the
complete file data is requested (start == 0 and
length == -1). Default is decrypted.ZIP_FL_UNCHANGEDUpon successful completion, the created source is returned.
Otherwise, NULL is returned and the error code in
archive or error is set to
indicate the error.
zip_source_zip_file() and
zip_source_zip_file_create() fail if:
ZIP_ER_CHANGED]ZIP_ER_INVAL]ZIP_ER_MEMORY]zip_stat_index() and
zip_fopen_index().
libzip(3), zip_file_add(3), zip_file_replace(3), zip_source(5)
zip_source_zip_file() and
zip_source_zip_file_create() were added in libzip
1.10.0.
