|ZIP_SET_FILE_COMPRESSION(3)||Library Functions Manual||ZIP_SET_FILE_COMPRESSION(3)|
zip_set_file_compression() function sets the compression method for the file at position index in the zip archive to comp with the compression method specific comp_flags. The comp is the same as returned by zip_stat(3). For the comp argument, currently only the following values are supported:
ZIP_CM_DEFLATE, but flags are ignored.
NOTE: Only the deflate and store methods can be assumed to be universally supported.
The comp_flags argument defines the compression level, 1 being fastest compression and 9 highest. Allowed values are 0 (which uses the default compression for the algorithm) and 1-9, other values are undefined. Further compression method specific flags might be added over time.
The current compression method for a file in a zip archive can be determined using zip_stat(3).
zip_set_file_compression() fails if:
zip_set_file_compression() was added in libzip 0.11.
