<random>

Backports related to Standard Header <random>

#include <cxxomfort/random.hpp>
// or as part of:
#include <cxxomfort/backports.hpp>

Including the header brings up <random>'s features, accounting for eg.: location being std::tr1::random... where set up in C++03, as well as changes to their names in certain compiler versions before C++11 was finalized.

Interfaces

Interfaces defined in this section:

• default_random_engine - in cxxomfort defined as ranlux24_base for C++03.
• subtract_with_carry and its typedefs ranlux24_base and ranlux48_base , for pre-C++11 compilers.

If CXXOFLAG_USE_INTERNAL_TR1 is enabled for pre-C++03 compilers, the following features are also enabled:

• linear_congruential_generator for pre-C++03 compilers.
• subtract_with_carry_engine for pre-C++03 compilers.
• shuffle_order_engine and knuth_b for pre-C++03 compilers.

Interfaces repointed here for GCC and Clang:

• linear_congruent_engine and its named typedefs minstd , minstd0 , when they appear in TR1 with a different name.
• uniform_int_distribution , uniform_real_distribution , when they appear in TR1 with a different name.

Fixes / non-backport interfaces (cxxomfort::fix):

• randmo() - modulo-respecting call to rand().
• cxxomfort::fix::shuffle_order_engine - for broken std in MSVC 2010.
• cxxomfort::fix::knuth_b - for broken std in MSVC 2010.

Pending:

• generate_canonical complementary (C++11).
• uniform_int_distribution complementary (C++11).
• discrete_distribution complementary (C++11).
