ByRef Buffer ( ) As Byte,
ByVal Offset As Long,
ByVal Count As Long,
Optional ByVal Callback As AsyncCallback,
Optional ByRef State As Variant ) As IAsyncResult
Parameters
- Buffer
-
[ByRef]
Byte.
The source array to copy the bytes from into the stream.
- Offset
-
[ByVal]
Long.
The starting index in the source Buffer to begin copying from.
- Count
-
[ByVal]
Long.
The maximum number of bytes to be copied into the stream.
- Callback
-
[ByVal]
Optional.
AsyncCallback.
A user supplied object to be notified of the finish of the writing.
- State
