SMSG_COMPRESSED_UPDATE_OBJECT

Description of the MangosTwo packet SMSG_COMPRESSED_UPDATE_OBJECT

Usage

This is compressed with the standard LZ77 algorthim and Huffman coding. It however does not work with all Deflate implementations. zlib a C/C++ library can decompress the buffer, as well as a zlib .NET port called #ziplib SharpZipLib. SMSG_COMPRESSED_UPDATE_OBJECT header is directly folled by an uint32 integer, containing the length of the uncompressed buffer. It can be used to allocate enough space for infalting/decompressing the compressed data. This integer is however not part of the compressed data or the deflate specification ([http://www.google.com/search?q=rfc+1951 rfc 1951]).
