Alignment
A way of aligning memory storage through template parameters.
____________________________________________________________________________________________________
type_with_alignment
Returns a fundamental type that has the same alignment as that specified in the template parameter.
template <const size_t ALIGNMENT>
class type_with_alignment
Example
typedef etl::type_with_alignment<4>::type type_t;
____________________________________________________________________________________________________
aligned_storage
Creates a memory store of the specified length at the specified alignment.
template <const size_t LENGTH, const size_t ALIGNMENT>
struct aligned_storage;
Example
// Creates aligned storage of length 100 at an alignment of 8.
etl::aligned_storage<100, 8>::type storage;
The class defines various conversion operators for ease of use.
Conversions are supplied to T&, const T&, T*, const T*, plus explicit get_address and get_reference member functions.
____________________________________________________________________________________________________
aligned_storage_as
Creates a memory store of the specified length at the same alignment as the specified type.
template <const size_t LENGTH, typename T>
struct aligned_storage_as;
Example
// Creates aligned storage of length 100 at an alignment of a double.
etl::aligned_storage_as<100, double>::type storage;

bool is_aligned(void* p, size_t alignment)
Check that p has alignment

Check that p has Alignment
____________________________________________________________________________________________________
template <typename T>
bool is_aligned(void* p)
Check that p has the alignment of T
