描述
get_serialized_item_ptrget_serialized_item_ptrGetSerializedItemPtrGetSerializedItemPtrGetSerializedItemPtrget_serialized_item_ptr returns the data pointer to the
serialized item which is passed by the handle
SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item
for an introduction of the basics of serialization). The
data pointer, i.e., the beginning of the serialized item is returned
by the parameter PointerPointerPointerPointerpointerpointer. The size of the serialized item
in bytes is passed by the parameter SizeSizeSizeSizesizesize.
运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
