DotNetCompression Class Reference for Windows Phone
BeginRead Method (Lzf4InputStream)






The buffer to write the decompressed bytes.
The offset in the buffer at which decompressed data will placed.
The maximum number of bytes to decompress.
An optional asynchronous callback, to be called when the operation is complete.
A user-provided object that distinguishes this particular asynchronous read request from other requests.
Initiates asynchronous read operation which reads bytes from the compressed stream and writes decompressed bytes into the specified buffer.

Parameters

buffer
The buffer to write the decompressed bytes.
offset
The offset in the buffer at which decompressed data will placed.
count
The maximum number of bytes to decompress.
callback
An optional asynchronous callback, to be called when the operation is complete.
state
A user-provided object that distinguishes this particular asynchronous read request from other requests.

Return Value

An object that represents the asynchronous read operation, which could still be pending.
