Detailed Description

A structure holding details about a memory-mapped file or device.

Such a structure is the resource type of a w::mmap_handle RAII handle.

Constructor & Destructor Documentation

memory_region() [1/2]

constexpr w::memory_region::memory_region ( void *  address, std::size_t  length  )

inlineconstexprnoexcept

Constructs a memory region.

Parameters

address	The (actual, not requested) base address of the mapping.
The	length of the mapping in bytes.

memory_region() [2/2]

constexpr w::memory_region::memory_region ( )

inlineconstexprnoexcept

Constructs an empty memory region.

Member Function Documentation

operator!=()

constexpr bool w::memory_region::operator!= ( const memory_region &  rhs ) const

inlineconstexprnoexcept

Compares two memory regions.

Parameters

rhs	A reference to the memory region to compare.

Returns

false if this object and rhs both have the same address and length.

Member Data Documentation

address

void* w::memory_region::address

The (actual, not requested) base address of the mapping.

length

std::size_t w::memory_region::length
