The true face of function pointer in single chip microcomputer and the operation of callback function

At this time, the north gate and the South Gate of the temple are opened at the same time , Coming from the north gate is a red haired evil man , On his left is the haze with ice in purple eyes , On the right is playful Na , Every step has a beautiful shadow ( I think it's fast , On the contrary, she has the ability to compress time and space , It just took a little time ); The blue haired man in the South Gate felt the evil eyes coming from a few light years away , Tell Shu He's coming , Shu Yan, I think I will play time and space , The ray beside the eye said, does my sister have the heart to let me treat that cold big ice ？ Words just fall light years away from the haze directly absolute zero , If it weren't for the temple light , Estimated ice age . But Ray said , Tut Tut was angry , If you are angry, you will not be cold , Only in this way can we have the value of fighting . Shu also said that sister Lei should be careful , That ice girl has more than this strength . Look at the lazy man and say , We are sorry for that red hair , It took Lanfa hundreds of millions of years to say that he couldn't fight , That person should be as strong as me in using callback functions , He should also be a player at the operating system level , And it won't let our star field infighting , This is red hair, light years away , But I feel talking in my ear , Are you so sure I won't hit you ？ Blue hair is waking up , If you also want to help famine, you won't do so , Evil men laugh well, I can't fight , But my wife wants to try with that man , Red hair directly brought LAN and Na to the eyes . Look ugly , But Lan said, let's work together , Red hair says yes ; In a flash, space collapses , But it only collapses in open areas , There is no influence around the eyes , In a flash, Na's soul was hurt , No matter how slow the time is , The sword Qi cut her instantly . Red hair then gently stroked Na's spirit , Directly recovered . It is indeed the ghost of the sword emperor . If I hadn't called back Na's spiritual body , The spirit body is probably useless ......
