system("pause");return0; } 首先利用lua提供的函数luaL_dofile来执行一个lua脚本。 可以看到有两个过程,首先luaL_loadfile函数将lua文件加载进来然后进行词法语法语义分析,得到一个closure函数放入栈中,接着调用lua_pcall函数来执行栈顶的closure。 我们先来看看第一个过程: ...

‘mutable’ node, which the programmer explicitly expects to change. Lua iterators likepairs()can now return specifically mutable nodes. The programmer can convert this to an immutable node if they want to store it for use after the loop, or they can test for mutability using theismutable()...
