In the VC knowledge Base I learned a lot of knowledge, a very short time I mastered the VC, mainly in your station under a lot of source code back analysis, learning. Look at you. A person will be net send package to the source code of mass message, have seen the internet, such as mass message software to buy, so feel oneself to write a mass message small program. Characteristics: VC source code, based on the IP/UDP protocol sock programming, accord

Use sock technology to send mail without server support. The speed is fast!! Copy Code code as follows: function Send_mail ($to, $subject, $body) { SMTP information that can be modified to your////////// $loc _host = "Longbill"; The computer name of the letter, can be arbitrary $SMTP _ACC = "Longbill.mail"; The user name of the SMTP authentication, $SMTP _pass = "Longbill"; SMTP authenticated password, $SMTP _host = "smtp.163.com";

When you link a MySQL database to a MySQL server on this computer, It's always going to be oh. Mysql.sock does not exist, resulting in a problem that cannot be linked, because if you specify localhost as a hostname, mysqladmin defaults to using the

); return 0;}In addition, in order to keep track of the flag bits in the Fossa total ns_mgr_poll function, the Ns_mgr_poll code in MONGOOSE.C is modified and the corresponding debug output information is added. The specific changes are as follows: time_t ns_mgr_poll (struct ns_mgr *mgr, int milli) {int loop=0; struct ns_connection *conn, *tmp_conn; struct Timeval TV; Fd_set Read_set, Write_set; sock_t max_fd = Invalid_socket; time_t current_time = time (NULL); Fd_zero (read_set); Fd_zer

Two Protocols TCP and UDPThe former can be understood as a guaranteed connection, and the latter is the pursuit of fast connections.Of course, the last point is a bit too absolute, but now do not have to boil too much, because the first socket programming, basics.A little imagine can be roughly understood, TCP is the pursuit of reliable transmission of data, UDP is the pursuit of fast data transmission.The former has a cumbersome connection process, while the latter is simply not establishing a

Analyze the socket creation process today About how the user-mode socket enters the kernel state to sys_socke through the system call, so we will not analyze it here. Let's look at the kernel-mode socket entry.

Http://www.jianshu.com/p/5d82a685b5b6After a long analysis of the socket creation source, found a piece of paste, so this summary, my blog at the same time there is another detailed source analysis, the kernel version of 3.9, it is recommended that after reading this article if you are interested in another blog post. Never look at another article alone.One: Call chain:Two: Data structureTake a look at the meaning of each data structure:1) socket, sock
