[英]Lua userdata alignment
How does lua_newuserdata align the allocated memory? lua_newuserdata如何对齐分配的内存? Does it depend on malloc/calloc, or does it do it's own thing?
它依赖于malloc / calloc还是自己做的? Is there any way to guarantee alignment without having to add code for this?
有什么方法可以保证对齐而不必为此添加代码?
Writing alignment code myself isn't a problem, but if it's not needed then I'd rather not, of course. 自己编写对齐代码不是问题,但是如果不需要,那么我当然不会。
All memory allocation in Lua is done throughout a user-supplied allocator given when you create a state with lua_newstate
. 当您使用
lua_newstate
创建状态时,Lua中的所有内存分配都是在用户提供的整个分配器中 lua_newstate
。
If you use luaL_newstate
instead of lua_newstate
, then Lua uses a memory allocator based on realloc
. 如果您使用
luaL_newstate
而不是lua_newstate
,那么Lua将使用基于realloc
的内存分配器 。
