/* RDG_genOut
|
||
|
|
Generate 'size' bytes of compressible data into stdout.
|
||
|
|
Compressibility can be controlled using 'matchProba'.
|
||
|
|
'LitProba' is optional, and affect variability of bytes. If litProba==0.0, default value is used.
|
||
|
|
Generated data can be selected using 'seed'.
|
||
|
|
If (matchProba, litProba and seed) are equal, the function always generate the same content.
|
||
|
|
|
||
|
|
RDG_genBuffer
|
||
|
|
Same as RDG_genOut, but generate data into provided buffer
