Lua 标准库（standard libraries）

一、Lua十标准大库：

basic library、coroutine library、package library、string manipulation、basic UTF-8 support、table manipulation、mathematical functions、input and output、operating system facilities、debug facilities.

To have acces to these libraries, the C host program should call the luaL_openlibs functions, which opens all standard libraries. Alternatively, the host program can open them individually by using luaL_requiref to call luaopen_base、luaopen_coroutine、luaopen_package、luaopen_string、luaopen_utf8、luaopen_table、luaopen_math、luaopen_io、luaopen_os、luaopen_debug. These functions are declared in lualib.h.

例子：

1）创建lua虚拟机

lua_State *lua_state = luaL_newstate();

2）加载Lua库

a、luaL_openlibs(lua_state);

b、luaL_requiref(lua_state, "base", luaopen_base, 1);

    lua_pop(lua_state,1);
