This version of
mallocallocates typed uninitialized storage associated with a given system.The following code snippet demonstrates how to use
mallocto allocate a range of memory to accommodate integers associated with Thrust’s device system.#include <thrust/memory.h> ... // allocate storage for 100 ints with thrust::malloc const int N = 100; thrust::device_system_tag device_sys; thrust::pointer<int,thrust::device_system_tag> ptr = thrust::malloc<int>(device_sys, N); // manipulate memory ... // deallocate ptr with thrust::free thrust::free(device_sys, ptr);

- Parameters:
system – The Thrust system with which to associate the storage.
n – The number of elements of type
Twhich the storage should accommodate.
- Template Parameters:
DerivedPolicy – The name of the derived execution policy.
- Returns:
If allocation succeeds, a pointer to an allocation large enough to accommodate
nelements of typeT; a null pointer otherwise. The pointer must be deallocated withthrust::free.- Pre:
DerivedPolicymust be publicly derived fromthrust::execution_policy<DerivedPolicy>.
