GetMaxCompressedLen-- Pass in the length of the source buffer and it returns the maximum size needed for the compressed output. It should not be too shocking to learn that after running a lossless compression function, it is possible for the output to be larger than the input. Compression ...
The second nibble of the token[f]holds the size of the match data minus 4; this tells the decompressor how many bytes to repeat from the already uncompressed data. If the literal length is 15 (maximum value), then more length data follows the token (immediately). Each byt...
static length and the uncompressed block length to decide the shortest option. If the block is the last block of the file, the program will perform one more test. It will compare the expected overall length of the compressed file to the original size of the uncompressed file. If it is lon...

then provide compressed data as a single memory block. Filesize provides the size of compressed data. This convention has obvious limitations (memory storage, size limit, concatenation, etc.), but it's damn simple. I suspect it was selected by several ports such as Java, Python and Perl, ...
