Qingming Holiday three days did not out of the bedroom door, first put the independent blog toss good. The domain name is not well filed. Domain name is ilovecpp.com, meaning "I love C + +", good shy, hide face, escape:). Words cnblogs.com the interface is ugly. Most of the rest of the time is to toss this small project, Unix kernel functions of various structures, flags even check man manual or look at the head big. Fortunately, it has been achieved.

Knowledge points to use:

1. Unix System IO Open Lseek write read
2. Process Control includes vfork (), waitpid ...
3. Signal operation (say the server side of the signal operation can be signal is completely enough, I still take a step, plus sigaction, and sigqueue, have time, wayward ⊙﹏⊙)
4. The most important thing is the message queue, the delivery is OK, received in the mtype on a lot of circles, the code has specific comments.

Code or tomorrow, now "April 7, 2015 02:13:59", the time is really fast. Mom eggs have classes in the morning and go to bed.
