YII Source Code Analysis (2) the previous article briefly analyzed the yii process, from creating an application to outputting results on the screen. This time I came up with a little more complicated, focusing on the output. it is no longer a simple line of helloworld, but it needs to be processed by the view layer. It is still the demos Directory. this time we chose hangman, a simple guessing game. The ol

Here fixedbit was neglected, and before that, fixedbit was guarded. See lstate. C's 153 rows (lua_newstate function ):
g->currentwhite = bit2mask(WHITE0BIT, FIXEDBIT);
It is easy to understand that all the root data of the Lua world is stored in this object. If it is cleared early, the code on the back will have a q
