device_new(p, n=1)#

template<typename T>
device_ptr<T> thrust::device_new(
device_ptr<void> p,
const size_t n = 1,
)#

device_new implements the placement new operator for types resident in device memory. device_new calls T’s null constructor on a array of objects in device memory. No memory is allocated by this function.

device_ptr

Parameters:

  • p – A device_ptr to a region of device memory into which to construct one or many Ts.

  • n – The number of objects to construct at p.

Returns:

p, casted to T’s type.

device_new(p, exemplar, n=1)#

template<typename T>
device_ptr<T> thrust::device_new(
device_ptr<void> p,
const T &exemplar,
const size_t n = 1,
)#

device_new implements the placement new operator for types resident in device memory. device_new calls T’s copy constructor on a array of objects in device memory. No memory is allocated by this function.

Parameters:

  • p – A device_ptr to a region of device memory into which to construct one or many Ts.

  • exemplar – The value from which to copy.

  • n – The number of objects to construct at p.

Returns:

p, casted to T’s type.

device_new(n=1)#

template<typename T>
device_ptr<T> thrust::device_new(
const size_t n = 1,
)#

device_new implements the new operator for types resident in device memory. It allocates device memory large enough to hold n new objects of type T.

Parameters:

n – The number of objects to allocate. Defaults to 1.

Returns:

A device_ptr to the newly allocated region of device memory.
