Must provide more input and/or consume the output (providing (for example if an input file is mmap'ed), or can be done byĬalls of the compression function. (deflation) but other algorithms will be added later andĬompression can be done in a single step if the buffers are This version of the library supports only one compression The zlib compression library provides in-memory compressionįunctions, including integrity checks of the uncompressed data.
