Will the registry key be leakage if the function ReCloseKey fails?

On MSDN, the description of the failed return value of the funciton ReCloseKey is below, in which does not state whether the key will be leaked.

A nonzero error code defined in Winerror.h indicates failure. To get a generic description of the error, callFormatMessage with the FORMAT_MESSAGE_FROM_SYSTEM flag set. The message resource is optional; therefore, if you callFormatMessage it could fail.

Will the register key be leakage if the function ReCloseKey fails? If yes, what is the reason?

I use Visual Studio 2005 to develop my application, which is running on Windows Server 2008 R2 standard. Recently we were reported a hanle leak issue, it was identified as a registry key leakage. Our program looks good, we open a registry key, then write some value to it, then close it. The code path has been tested on my lab, no issue was find.

Thanks,
