Function Documentation

Atlas::PRegion* NVM_GetRegion

(

uint32_t

rid

)

Get a handle to a persistent region.

Parameters

rid	Region identifier

Returns

Pointer to the corresponding persistent region

Currently, this interface is to be used by a client only for the placement new operations

void* operator new ( size_t  sz, Atlas::PRegion *  rgn  )

noexcept

Object allocation for C++.

Parameters

sz	Allocation size
rgn	Pointer to the region to serve the allocation from

Returns

Pointer to memory allocated

This interface overloads the C++ placement new operator. The corresponding delete operation is NVM_Destroy.

void* operator new[] ( size_t  sz, Atlas::PRegion *  rgn  )

noexcept

Array form allocation for C++, type must have explicit destructor.

Parameters

sz	Allocation size
rgn	Pointer to the region to serve the allocation from

Returns

Pointer to memory allocated

This interface overloads the array form C++ placement new operator. The type of the array elements must have an explicit destructor. The corresponding delete operation is NVM_Destroy_Array.
