Study Notes on Unix Network Programming Based on TCP socket programming 1. socket Functions Int socket (int family, int type, int protocol) Returns a socket descriptor. Error returned-1 Family indicates the protocol family. Generally, IPv4 is AF_INET and IPv6 is AF_INET6. Type specifies the socket type, and the byte stream is SOCK_STREAM. The datagram is SOCK_DG

Obviously, this kind of work is not for everyone to be competent. The source of knowledge seems to be a lot of ways, but in fact there can only be a real source, that is, their own practice. Not through their own practice and thinking, knowledge even if ot

UNIX network programming is indeed a rare book. Its advantage lies not only in its thorough theory, but also in its clear programming examples. To put it bluntly, when I first started viewing the three sets of Unix programming, I

responded to the cancellation request of the main thread after setting the Pthread_cancel_disable state to the new one.2.2 Types that can be canceledThe above-mentioned thread will check to see if it is canceled when it arrives at a cancellation point. This type of cancellation is also known as deferred cancellation. In addition, there is a cancellation type that is asynchronous cancellation. When a thread's cancellation type is asynchronous, the thread can be canceled at any time.A thread can

main reasons: 1. I think it will certainly be involved in future project development, so there is no need to spend time alone; 2. after I bought the book UNIX network programming, I wanted to use my spare time to study it. However, I usually don't have time to learn such complicated things, I had to configure the Source Code compiling environment before I had to
