ReadData(Int64, Byte[], MEByteSourceReadBytesCallback)
Read data asynchronously into a byte array.
public void ReadData(long offset, byte[] data, MediaExtension.MEByteSourceReadBytesCallback completionHandler);member this.ReadData : int64 * byte[] * MediaExtension.MEByteSourceReadBytesCallback -> unitParameters
- offset
- Int64
The offset (relative to the start of the ifle) where to start reading.
- data
- Byte[]
The byte array to write the data into.
- completionHandler
- MEByteSourceReadBytesCallback
The delegate which is called when the read operation has completed.
Remarks
This overload will try to fill the data byte array with data.
