In fact, as early as the DOS era, there was an API concept, but at that time the API was provided in the form of Interrupt calls (INT 21 h, all applications running under DOS use the operating system functions directly or indirectly through interrupt calls, for example, if you set Ah to 30 h and call int 21 h, you can get the dos OS version number. In Windows, system APIs are provided through function calls. In Win
