So how to fix it, the blog behind me may give an ans

system is assigned to the SCHED_RR process time slices, and then polls the process to run the process, putting the elapsed time slice to the end of the queue. Due to the existence of a variety of scheduling methods, Linux process scheduling using "conditional deprivation" scheduling mode. The common process is to use the Sched_other time slice polling method, the real-time process can deprive the ordinary process. If the normal process is running in

TCP segment or UDP segment, the TCP or UDP protocol then determines which user process should be given the application-tier data according to the port number field of the TCP header or UDP header. The IP address is the address that identifies different hosts on the network, and the port number is the address on the same host that identifies the different processes, and the IP address and port number together identify the only process in the

In order to complete the compilation first, the following steps are required:1. Go to the Linux subdirectory and perform make. (This step is patching.) ）2, return to the previous level directory, open file simplec.c, add header file #include 3.

Linux Network Programming socket options so_linger, so_reuseaddr In Linux network programming, there are many socket options. Several of the most important options are: so_linger (only applicable to TCP and sctp), so_reuseaddr.

From http://blog.csdn.net/feiyinzilgd/article/details/5894300In Linux network programming, there are many options for sockets. Several of the more important options are: So_linger (only for TCP,SCTP), so_reuseaddr. So_linger By default, when you call close to close the use of Socke, close returns immediately, but if there is data in send buffer, the
