Description: reads up to length bytes from the file pointer referenced by handle.

Reading stops when up to length bytes have been read, EOF (end of file) is
|
||
|
reached, (for network streams) when a packet becomes available, or (after
|
||
|
opening userspace stream) when 8192 bytes have been read whichever comes first.
