这是《Lua程序设计》中的例子，做个简单记录。
#include
#include
#include
static void stackDump(lua_State *L){ int i; int top = lua_gettop(L); for(i = 1; i <= top; i++){ int t = lua_type(L, i); switch(t){ case LUA_TSTRING: printf("'%s'", lua_tostring(L, i)); break; case LUA_TBOOLEAN: printf(lua_toboolean(L, i) ? "true":"false"); break; case LUA_TNUMBER: printf("%g", lua_tonumber(L, i)); break; default: printf("%s", lua_typename(L, t)); break; } printf(" "); } printf("\n"); } int main(void){ lua_State *L = luaL_newstate(); lua_pushboolean(L, 1); lua_pushnumber(L, 10); lua_pushnil(L); lua_pushstring(L, "vonzhou"); stackDump(L); // dump the stack lua_pushvalue(L, -4);// push the value of the index to the stack stackDump(L); lua_replace(L, 3); // pop a value and replace the index's stackDump(L); lua_settop(L, 6); // set the top index, fill 'nil' stackDump(L); lua_remove(L, -3); // stackDump(L); lua_settop(L, -5); stackDump(L); lua_close(L); return 0; }
运行结果：
简单画个示意图：
