Retrieves the size, in bytes, of a specified stream.
Type: IStream*
A pointer to the IStream interface of the stream whose size is to be determined.
Type: ULARGE_INTEGER*
A pointer to a ULARGE_INTEGER structure to receive the size of the stream.
Type: HRESULT
Returns S_OK on success or a COM failure code otherwise. See IStream::Stat for further discussion of possible error codes.
This function gets the size of the stream by calling the specified stream object's IStream::Stat method. It then copies the value of the cbSize member of the STATSTG structure returned by IStream::Stat to the ULARGE_INTEGER structure pointed to by pui. If the function fails, the contents of the ULARGE_INTEGER structure are undefined.
