循环中的迭代(Iterations In From Loop)

 
 
 在32位和64位Windows中， LoadLibrary在失败时返回NULL 。 
 
 
 在16位Windows中LoadLibrary返回一个小于32的值来表示失败。 
 
 
 KB142814显然是从16位Windows日期开始的，如果仔细观察，您会看到一个kb16bitonly关键字。 我认为假设您不再开发16位Windows是安全的！ 
 
 Raymond Chen在这件事上的一些相关文章： 
 
 
 
 HINSTANCE和HMODULE有何区别？ 
 
 
 我可以用ShellExecute函数返回的HINSTANCE做什么？ 
 
 
 LoadLibrary的现代文档位于： https ： //msdn.microsoft.com/en-us/library/windows/desktop/ms684175.aspx ，这是您问题中的第一个链接。 它说： 
 
 
 
 返回值 
 
 
 如果函数成功，则返回值是模块的句柄。 
 
 
 如果函数失败，返回值为NULL。 要获得扩展的错误信息，请调用GetLastError。 
 

 
 
In 32 and 64 bit Windows, LoadLibrary returns NULL on failure. 
 
 
In 16 bit Windows LoadLibrary returns a value less than 32 to indicate failure. 
 
 
KB142814 clearly dates from the 16 bit Windows days, and if you look closely you will see a kb16bitonly keyword. I think it is safe to assume that you are not developing for 16 bit Windows anymore!
 
Some relevant articles from Raymond Chen on this matter:
 
 
 
What is the difference between HINSTANCE and HMODULE?
 
 
What can I do with the HINSTANCE returned by the ShellExecute function?
 
 
The modern day documentation for LoadLibrary is here: https://msdn.microsoft.com/en-us/library/windows/desktop/ms684175.aspx, that is the first link in your question. It says:
 
 
 
Return value
 
 
If the function succeeds, the return value is a handle to the module.
 
 
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
