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