Detailed Description

template<typename ToType, typename CBRNG>
struct r123::ReinterpretCtr< ToType, CBRNG >

ReinterpretCtr uses memcpy to map back and forth between a CBRNG's ctr_type and the specified ToType. For example, after:

typedef ReinterpretCtr<r123array4x32, Philox2x64> G;

G is a bona fide CBRNG with ctr_type r123array4x32.

WARNING: ReinterpretCtr is endian dependent. The values returned by G, declared as above, will depend on the endianness of the machine on which it runs.
