1. Introduction
Alas! Is Socket programming frustrating to you? Is it difficult to obtain useful information from man pages? But you are overwhelmed by the bind () structure before calling connect? Wait...

Fortunately, I have completed these tasks and I will share my knowledge with everyone. If you understand the C language and want to pass through the swamp of network programming, you are right.

I finally caught up with the future (at the last moment) and updated the IPv6 guide! Enjoy!

1.1 audience

This document is a guide rather than a reference book. If you are new to socket programming and want to find an entry book, you are my reader. But this is not a complete socket programming book.

1.2 platform and Compiler

Most of the Code in this document is successfully compiled on the Linux platform PC using GNU gcc.

1.3 Official Website

1.4 attention should be paid to Solaris/SunOS programmers

When compiling on Solaris or SunOS, you must have more parameters. As shown below:

$ Cc-o server. c-lnsl-lsocket-lresolv

1.5 Windows programmer's note

You must add the following header file (unless you have installed Cygwin)

# Include <winsock. h>

In addition, WSAStartup () must be called first, as shown below:

# Include <winsock. h>

...

{

WSADATA wsaData; // if this doesn't work

// WSData wsaData; // then try this instead

// MAKEWORD (1, 1) for Winsock 1.1, MAKEWORD (2, 0) for Winsock 2.0:

If (WSAStartup (MAKEWORD (1, 1), & wsaData )! = 0 ){

Fprintf (stderr, "WSAStartupfailed. \ n ");

Exit (1 );

}

}

 

Finally, you must call WSACleanup ().

End.
