Detailed Description

A wrapper class for host and/or device pointers, allowing easy access to CUDA's pointer attributes.

Note

at the moment, this class is not used by other sections of the API wrappers; specifically, freestanding functions and methods returning pointers return raw T*'s rather than pointer_t<T>'s. This may change in the future.

Todo:

Consider allowing for storing attributes within the class, lazily (e.g. with an ::std::optional).

Function Documentation

wrap()

template<typename T >

pointer_t<T> cuda::memory::pointer::wrap ( T *  ptr )

inlinenoexcept

Wraps an existing pointer in a pointer_t wrapper.

Parameters

ptr	a pointer - into either device or host memory - to be wrapped.
