c - Lua C API : pushing function with lua_pushcfunction isn't working

Question

它只是崩溃了，我需要你来解决它。提前致谢。

typedef lua_CFunction luaFunc;

int Caller(lua_State* luaVM)
    luaFunc Func = lua_tocfunction(luaVM, 1);

    lua_pushcfunction(luaVM, Func);
    lua_call(luaVM, 0, 0);
    return 0;
}

在 Lua 中它应该是这样的:

function Caller(f)
    f()
end

Answer 1

相当于 Lua 代码

function Caller(f)
    f()
end

是

int Caller(lua_State* luaVM)    
    lua_call(luaVM, 0, 0);
    return 0;
}
