Detailed Description

template<int N>
struct trailing_wide_ints< N >

A variable-length array of wide_int-like objects that can be put
at the end of a variable-sized structure.  The number of objects is
at most N and can be set at runtime by using set_precision().

Use extra_size to calculate how many bytes beyond the
sizeof need to be allocated.  Use set_precision to initialize the
structure.

extra_size() [1/2]

template<int N>

size_t trailing_wide_ints< N >::extra_size ( ) const

inline

References trailing_wide_ints< N >::extra_size(), trailing_wide_ints< N >::m_num_elements, and trailing_wide_ints< N >::m_precision.

Referenced by prange_storage::alloc(), and trailing_wide_ints< N >::extra_size().

extra_size() [2/2]

template<int N>

size_t trailing_wide_ints< N >::extra_size ( unsigned int precision, unsigned int num_elements = N )

inlinestatic

Return how many extra bytes need to be added to the end of the
structure in order to handle NUM_ELEMENTS wide_ints of precision
PRECISION.  NUM_ELEMENTS is the number of elements, and defaults
to N.

operator[]() [1/2]

template<int N>

trailing_wide_int trailing_wide_ints< N >::operator[] ( unsigned int index )

inline

Return a reference to element INDEX.

inline

set_precision()

template<int N>

void trailing_wide_ints< N >::set_precision ( unsigned int precision, unsigned int num_elements = N )

inline

Initialize the structure and record that all elements have precision
PRECISION.  NUM_ELEMENTS can be no more than N.
