参照C / C Lua的功能++ [英] Reference to Lua function in C/C++
问题描述
我有一个功能于一组表格嵌套比较深。有没有在C / C ++的方式来得到一个参考,以该功能,推动了(和args)压入堆栈,当我需要使用它吗?
I have a functions nested relatively deeply in a set of tables. Is there a way in C/C++ to get a "reference" to that function and push that (and args) onto the stack when I need to use it?
推荐答案
这是什么参考系统是。函数调用 R = luaL_ref(L,LUA_REGISTRYINDEX)
存储在注册表中的堆栈顶部的值,并返回可以存储在C面,并用一个整数检索与函数调用值 lua_rawgeti(L,LUA_REGISTRYINDEX,R)
。
This is what the reference system is for. The function call r = luaL_ref(L, LUA_REGISTRYINDEX)
stores the value on the top of the stack in the registry and returns an integer that can be stored on the C side and used to retrieve the value with the function call lua_rawgeti(L, LUA_REGISTRYINDEX, r)
.
查看 PIL章,还有的 luaL_ref()
,的 lua_rawgeti()
和的 luaL_unref()
以完整的故事。
See the PiL chapter, as well as the documentation of luaL_ref()
, lua_rawgeti()
, and luaL_unref()
for the full story.
