Detailed Description

template<typename T>
class thrust::device_ptr< T >

device_ptr stores a pointer to an object allocated in device memory. This type provides type safety when dispatching standard algorithms on ranges resident in device memory.

device_ptr has pointer semantics: it may be dereferenced safely from the host and may be manipulated with pointer arithmetic.

device_ptr can be created with the functions device_malloc, device_new, or device_pointer_cast, or by explicitly calling its constructor with a raw pointer.

The raw pointer encapsulated by a device_ptr may be obtained by either its get method or the raw_pointer_cast free function.

Note

device_ptr is not a smart pointer; it is the programmer's responsibility to deallocate memory pointed to by device_ptr.
