virtual bool pxtask::NvCudaBuffer::free

(

)

[pure virtual]

Releases the buffer and the memory it used, returns true if successful.

virtual CudaMemoryManager* pxtask::NvCudaBuffer::getCudaMemoryManager

(

)

const [pure virtual]

Retrieves the manager over which the buffer was allocated.

virtual CudaBufferPtr pxtask::NvCudaBuffer::getPtr

(

)

const [pure virtual]

Returns the pointer to the allocated memory.

virtual size_t pxtask::NvCudaBuffer::getSize

(

)

const [pure virtual]

Returns the size of the allocated memory.

virtual const CudaBufferType& pxtask::NvCudaBuffer::getType

(

)

const [pure virtual]

Returns the type of the allocated memory.

virtual bool pxtask::NvCudaBuffer::realloc	(	size_t	size,
		NV_ALLOC_INFO_PARAMS_DECL(NULL, 0, NULL, UNASSIGNED)
	)			[pure virtual]

Realloc memory. Use to shrink or resize the allocated chunk of memory of this buffer. Returns true if successful. Fails if the operation would change the address and need a memcopy. In that case the user has to allocate, copy and free the memory with separate steps. Realloc to size 0 always returns false and doesn't change the state.
