LoadLibrary在失败时返回NULL还是错误代码<32？(Does LoadLibrary return NULL or an error code < 32 on failure?)

 MSDN文档声明 
 
 
 
 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 。 
 
 
 而Microsoft支持的返回值小于32的列表指示错误 
 
 
 
 API函数LoadLibrary加载一个DLL并返回句柄或错误代码。 如果返回值小于32，则表示下面列出的错误之一。 返回值大于或等于32表示成功，您应该调用FreeLibrary函数来卸载库。 
 
 
 第二篇文章是在2003年上次审查的，明确地适用于Visual Basic 4.0。 
 
 什么是正确的？ LoadLibrary返回!= 0或>= 32是否成功？ 或者都是正确的，我缺少一些与C风格界面不同的版本差异或VB特定Windows API包装的提示？ 

The MSDN documentation states
 
 
 
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.
 
 
while Microsoft support has a list of return values less than 32 that indicate an error
 
 
 
The API function LoadLibrary loads a DLL and returns either a handle or an error code. If the return value is less than 32, it indicates one of the errors listed below. A return value greater than or equal to 32 indicates success and you should call the FreeLibrary function to unload the library.
 
 
The second article was last reviewed in 2003 and explicitly applies to Visual Basic 4.0.
 
What is correct? LoadLibrary returning != 0 or >= 32 for success? Or are both correct and I am missing some hint for a Version difference or a VB specific Windows API wrapper that differs from the C style interface?
