- * Compress in_len bytes stored at the memory block starting at

- * of out_len bytes.
- *
- * If the output buffer is not large enough or any error occurs return 0,
- * otherwise return the number of bytes used, which might be considerably
- * more than in_len (but less than 104% of the original size), so it
- * makes sense to always use out_len == in_len - 1), to ensure _some_
- * compression, and store the data uncompressed otherwise (with a flag, of
- * course.
- *
- * lzf_compress might use different algorithms on different systems and
- * even different runs, thus might result in different compressed strings
- * depending on the phase of the moon or similar factors. However, all
- * these strings are architecture-independent and will result in the
- * original data when decompressed using lzf_decompress.
- *
- * The buffers must not be overlapping.
- *
- * If the option LZF_STATE_ARG is enabled, an extra argument must be
- * supplied which is not reflected in this header file. Refer to lzfP.h
