此模块收集了最常用的API函数及相关数据类型、常量等，导入此模块之后可以直接在程序中使用API函数了，大大地方便了编程。



得益于易语言编译器的优化，易语言在编译成最终的二进制文件的时候，只会把用到的API函数、常量和数据类型编译进去，所以不会增加最终文件的大小。-This module is a collection of the most commonly used API functions and data types, constants, etc., can then import this module directly in the program using the API function, and greatly facilitate the programming.



　　Thanks to easy language compiler optimization, easy language, when compiled into the final binary file, only to use the API functions, constants and data types compiled, so it will not increase the size of the final document.
