API flags for API standards and the right to use them

API Standard - API is the English abbreviation of the American Petroleum Institute. Founded in 1919, API was the first national business association in the United States and one of the first and most successful standard-setting chambers in the world.

API standards mainly stipulate equipment performance, sometimes also include design and process specifications, standard development areas include oil production, refining, measurement, transportation, sales, safety and fire protection, environmental regulations, etc., its information technology standards include oil and gas industry EDI, communication and information technology applications.

One of the key tasks of API is to standardize equipment for the oil and gas industry to ensure the safety, reliability and interchangeability of the equipment used in the industry.

APIs, to put it mildly, are functions that are contained in a dynamic connection library file with an additional name called a dll. By standard definition, an API is a 32-bit application programming interface for Windows, a complex set of functions, messages, and structures that enable programmers to program applications that run on Windows 95 and Windows NT operating systems in different types of programming languages. Suffice it to say, if you've ever learned VC, then the API isn't a problem for you.

But if you haven't learned VC, or if you're not familiar with the architecture of Windows 95, then it's fair to say that learning the API will be a hard job.

If you open the Windows System folder, you can see that there are a lot of files with the name dll attached to it. There is not just one, dozens, or even hundreds of API functions contained in a DLL. Can we all master it?

The answer is no, it is impossible to master. But in fact, we really don't need to master everything, as long as we focus on mastering the API functions that come with the WinDos system itself. However, it is also necessary to discard functions that duplicate the functions of VB itself.

For example, the etattr command of vb can obtain the file attributes, and the setattr can set the file attributes. There are also corresponding functions for APIs.

GetFileAttributes and SetFileAttributes, both have similar performance. If you count it like this, there is only one left. Yes, no less.

But, I can tell you that if you are familiar with 100, you will be at least twice as good at programming as you are today. Although people say that VB and Windows have a close relationship, I think that the API is closer.

windows。If you learn the API, the first thing you will learn is an understanding of Windows architecture. This harvest is not easy to come by.

Summary. Hello, glad to answer for you. API standards mainly specify the equipment capacity, and sometimes also include design and process specifications.

Hello, glad to answer for you. API standards mainly specify the equipment capacity, and sometimes also include design and process specifications.

API standards mainly stipulate equipment and energy, and sometimes also include design and process specifications, and the standard formulation areas include oil production, refining, measurement, transportation, sales, safety and fire prevention, environmental regulations, etc., and its information technology standards include EDI, communication and information technology applications for the oil and gas industry. One of the key tasks of API is to standardize equipment used in the oil and gas industry to ensure that the equipment used in the industry is safe, reliable, and interchangeable. Founded in 1919, API is the first national business association in the United States, and one of the earliest and most successful chambers of commerce in the world.
