Writes information to a stream asynchronously. For example, the Shell implements this method on file items when transferring them asynchronously.
Type: const void*
A pointer to a buffer of size cb bytes that contains the information to be written to the stream.
Type: DWORD
The size of the buffer pointed to by lpBuffer, in bytes.
Type: LPDWORD
Pointer to a DWORD value that, when the method returns successfully, states the actual number of bytes written to the stream. This value can be NULL if this information is not needed.
Type: LPOVERLAPPED
A pointer to an OVERLAPPED structure that contains information used in the asynchronous write operation.
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
WriteAsync should reset the event specified by the hEvent member of the OVERLAPPED structure to a nonsignaled state when it begins the input/output (I/O) operation.
