get_memory_block_ptr( : : MemoryBlockHandle : Pointer, Size)

描述

get_memory_block_ptrget_memory_block_ptrGetMemoryBlockPtrGetMemoryBlockPtrGetMemoryBlockPtrget_memory_block_ptr returns the data pointer to the beginning of a memory block in PointerPointerPointerPointerpointerpointer and its size in bytes in SizeSizeSizeSizesizesize. MemoryBlockHandleMemoryBlockHandleMemoryBlockHandleMemoryBlockHandlememoryBlockHandlememory_block_handle is the handle of the memory block.

执行信息

多线程类型：可重入（与非独占算子并行运行）。
多线程作用域：全局（可从任何线程调用）。
未采用并行化处理。

参数
