Detailed Description

ScopedMemoryAllocation is a helper function for allocating memory blocks from the backend while adding the security and ease of use of the RAII idiom.

Usage notes: This is meant to be used only temporarily within a particular block of code. The class doesn't take a reference to the network backend. Check handle() for nullptr, which is the failure of allocation. Memory is freed automatically once out of scope.

Constructor & Destructor Documentation

ScopedMemoryAllocation()

nvneural::ScopedMemoryAllocation::ScopedMemoryAllocation ( INetworkBackend *  pBackend, size_t  bufferSize  )

inline

Creates a temporary memory allocation using a network backend.

The memory allocated is in the backend's address space (cuDevicePtr for CUDA).

Parameters

pBackend	Backend performing the allocation
bufferSize	Size of buffer to request, in bytes

Member Function Documentation

asPointer()

void* nvneural::ScopedMemoryAllocation::asPointer ( )

inline

Returns the pointer to the allocated memory block.

Returns

A void pointer to the memory block.

handle()

MemoryHandle nvneural::ScopedMemoryAllocation::handle ( ) const

inline

Returns the memory handle of the allocated memory block.

Returns

The memory handle, nullptr indicates a failed allocation.

operator=()

ScopedMemoryAllocation& nvneural::ScopedMemoryAllocation::operator= ( ScopedMemoryAllocation &&  moveFrom )

inline

Takes ownership of an allocation from another ScopedMemoryAllocation.

Parameters

moveFrom

rvalue reference to the source allocation object
