You didn't say whether you've checked your code for buffer
overruns.

The most efficient way would be to statically allocate the dictionary
and string tables. The downside is that you then need to serialise
the [de]compression.

dear everybody,
i am trying to compress/decompress ip packets.
for this i have implemented the adaptive lzw compression.
i put the code in the ip_output.c and do my compression/decompression
just before the if_output() function call so that i won't interfere with
the ip processing of the kernel.
