这些函式解决两个最棘手的记忆体配置问题：覆写配置之缓冲区的尾端和记忆体遗漏 （无法成功释放不再需要的配置）。
These functions solve two of the most difficult memory allocation problems: overwriting the end of an allocated buffer and memory leaks (failing to free allocations after they are no longer needed).
衍生类别中的函式试图覆写基底类别中的虚拟函式，但衍生类别函式没有与基底类别函式相同的传回型别。
