Where is ERROR_PENDING defined?

Question

The MSDN documentation for CommitTransactionAsync indicates it may produce an ERROR_PENDING error code. However, this error code does not seem to be defined in winerror.h, nor any other header reachable from ktmw32.h or windows.h (using the version of the Windows SDK included in Visual Studio 2010). In fact, I cannot find a single file containing the text ERROR_PENDING anywhere in the Windows SDK 7.1; manually going through the list of System Error Codes doesn't reveal it either. Where can I find the definition of this elusive error code?

Experimentation shows CommitTransactionAsync to produce ERROR_SUCCESS - is this a simple matter of the documentation being wrong?

It's a doc bug. @flashk's guess is correct: it can produce ERROR_IO_PENDING. I am submitting a bug to the doc owner today. Thanks!
