sycl::aligned_alloc_host
void* sycl::aligned_alloc_host( size_t alignment, size_t num_bytes, const sycl::context& ctxt );
template <typename T> T* sycl::aligned_alloc_host( size_t alignment, size_t count, const sycl::context& ctxt );
size_t alignment |
Specifies the byte alignment. Must be a valid alignment supported by the implementation. |
size_t num_bytes |
Number of bytes to allocate. |
size_t count |
Number of elements of type T to allocate. |
size_t count |
The SYCL context that contains the devices that will access the host allocation. |
Returns a pointer to the newly allocated host memory on success. Memory allocated by sycl::aligned_alloc_host must be deallocated with sycl::free in order to avoid memory leaks.
Returns nullptr on failure.
