This page covers the memory access properties extended API, providing types and functions for annotating memory accesses with cache residence hints such as access_property, annotated_ptr, and discard_memory.

cuda::access_property	Represents a memory access property	libhipcxx 1.6.0 / CCCL 2.0.0 / CUDA 11.5
cuda::annotated_ptr	Binds an access property to a pointer	libhipcxx 1.6.0 / CCCL 2.0.0 / CUDA 11.5
cuda::apply_access_property	Applies access property to memory	libhipcxx 1.6.0 / CCCL 2.0.0 / CUDA 11.5
cuda::associate_access_property	Associates access property with raw pointer	libhipcxx 1.6.0 / CCCL 2.0.0 / CUDA 11.5
cuda::discard_memory	Writes indeterminate values to memory	libhipcxx 1.6.0 / CCCL 2.0.0 / CUDA 11.5
