12 * Interface to packet compression for ssh.
22 * Initializes compression; level is compression level from 1 to 9 (as in

28 void buffer_compress_uninit();
31 * Compresses the contents of input_buffer into output_buffer. All packets
32 * compressed using this function will form a single compressed data stream;
33 * however, data will be flushed at the end of every call so that each
34 * output_buffer can be decompressed independently (but in the appropriate
35 * order since they together form a single compression stream) by the
36 * receiver. This appends the compressed data to the output buffer.

43 * stream; however, data will be flushed at the end of every call so that

45 * buffer_compress was called, and in the same order that buffers compressed
46 * with that. This appends the uncompressed data to the output buffer.
