SYNOPSIS

   Data Fields
       void * devicePointer

       __CUDA_DEPRECATED int isManaged
       __CUDA_DEPRECATED enum cudaMemoryType memoryType
       enum cudaMemoryType type

Detailed Description

       CUDA pointer attributes

Field Documentation

   void* cudaPointerAttributes::devicePointer
       The address which may be dereferenced on the current device to access the memory or NULL
       if no such address exists.

   void* cudaPointerAttributes::hostPointer
       The address which may be dereferenced on the host to access the memory or NULL if no such
       address exists.

       Note:
           CUDA doesn't check if unregistered memory is allocated so this field may contain
           invalid pointer if an invalid pointer has been passed to CUDA.

   __CUDA_DEPRECATED int cudaPointerAttributes::isManaged
       Deprecated

       Indicates if this pointer points to managed memory

   __CUDA_DEPRECATED enum cudaMemoryType cudaPointerAttributes::memoryType
       Deprecated

       The physical location of the memory, cudaMemoryTypeHost or cudaMemoryTypeDevice. Note that
       managed memory can return either cudaMemoryTypeDevice or cudaMemoryTypeHost regardless of
       it's physical location.

   enum cudaMemoryType cudaPointerAttributes::type
       The type of memory - cudaMemoryTypeUnregistered, cudaMemoryTypeHost, cudaMemoryTypeDevice
       or cudaMemoryTypeManaged.
