19/*!RDG_genBuffer
20   Generate 'size' bytes of compressible data into 'buffer'.
21   Compressibility can be controlled using 'matchProba', which is floating point value between 0 and 1.
22   'LitProba' is optional, it affect variability of individual bytes. If litProba==0.0, default value will be used.
23   Generated data pattern can be modified using different 'seed'.
24   For a triplet (matchProba, litProba, seed), the function always generate the same content.

26   RDG_genStdout
27   Same as RDG_genBuffer, but generates data into stdout
