Hello world, buffalohelloworld
A Chinese ajax framework defines the Transmission Basis for remote Web calls,
In addition, the remote call object is serialized locally to become an object that can be touched by JavaScript programming.
Configure the dependency package:
Configure web. xml<dependency><groupId>net.buffalo</groupId><artifactId>buffalo</artifactId><version>2.0</version></dependency>
Note: Since I installed it manually to the maven local repository and customized a coordinate, you can also directly put it under the WEB-INF/lib

This is because printf is Row-buffered (because it is connected to the terminal,/dev/ttys0, otherwise it is full-buffered ).
During fork, the io buffer of the parent process has not been cleared (or it may be a child process, but the order is not clear at this time .), Therefore, the output of the content of the Parent and Child processes is two hello world rows in one row.
After a line feed is added, printf caches the rows. Therefore, after fork, only one hello world will be removed.
You can add a sleep of 2 seconds before fork to see it clearly.
Refer to the section on standard I/O and Process Control for advanced unix programming.
