+   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
