telephony application programming interface

Through the understanding of IP address acquisition, due to the business is not very understanding, I use interface programming to achieve GetIP (): An interface is like a template that defines the methods that an object must implement in order for these methods to be referenced as interface instances.

, ignoring routing settings for the underlying protocol. (5) returnThe execution successfully returns the number of bytes actually sent, with an error of 1, and the error code is stored in errno.A successful execution simply means that the data is written to the socket's buffer and does not indicate that the data has been successfully sent over the network to the destination.8. RECV () Receive data#include #include ssize_t recv (int conn_fd,void *buf,size_t len,int flags)Recv () is used to

, have provided a large number of library and control in advance, and these functions is the architecture in the WIN32 API, is tantamount to encapsulating all the functions of the collection, so that the program designers can focus on the software functional design, Rather than the technical details of communicating with the operating system or other programs, it helps to accelerate application development. What is the Windows API The Windows API is

BKJIA Editor's note: we have introduced many articles related to iOS development and many mobile device design documents, but most of them are developers' experiences, for example, the three foundations required for iPhone application development are not official documents. This article is an updated iOS design document from. This is a design document prepared by the author and may be inaccurate in translation. If you are interested, you may also want

worry, we are about to enter the component programming stage.At that time, you read this article again based on the specific program code, but did not understand it? Oh... read again! Slowly, the old man understands this :-) Leave homework ......1. What is the iid of the idispatch interface? (Ah ~~~ Stupid. In the source program, right-click and execute go to definition)2. How many functions does the ipict

Original link: http://kb.cnblogs.com/page/145705/ Through the previous two, I think you have a certain understanding of the "interface-oriented programming" of the idea, and through the second example, to obtain a certain visual impression. However, the second example is designed to show the implementation of interface-oriented

This article Reprinted from: http://www.infomcu.com/Program/20071007/455_2.html Abstract:Download cables are widely used in the design and debugging of electronic systems. This article introduces its basic principles and programming control methods. For the list instances of the current single-chip microcomputer's ISP serial programming mode, it briefly introduces the serial

introducehey! Does Socket programming make you frustrated. Is it hard to get useful information from man pages? You want to keep up with the times to do an Internet program, but frown on the structure of BIND () before you call Connect (). ... Well, I'm here now, and I'm going to share my knowledge with everyone. If you understand the C language and want to go through the Web programming swamp, then you co

constantly abstracted, we will be farther and farther away from the system layer: The system layer will be gradually improved, and we will gradually be eliminated. The truth is that everyone can understand it. Therefore, we cannot always stay at the application layer. We need to enter the system layer, architecture design, system design, and so on are part of the work scope of the system layer. We have to enter the system layer to avoid a sense
