    1.13 +These functions convert relative addresses to absolute addresses
    1.14 +in CALL instructions to increase the compression ratio.
    1.15 +  
    1.16 +  In:
    1.17 +    data     - data buffer
    1.18 +    size     - size of data
    1.19 +    ip       - current virtual Instruction Pinter (IP) value
    1.20 +    state    - state variable for x86 converter
    1.21 +    encoding - 0 (for decoding), 1 (for encoding)
    1.22 +  
    1.23 +  Out:
    1.24 +    state    - state variable for x86 converter
    1.25 +
    1.26 +  Returns:
    1.27 +    The number of processed bytes. If you call these functions with multiple calls,
    1.28 +    you must start next call with first byte after block of processed bytes.
