Detailed Description

A class that implements IHandler to provide an asynchronous file reader that uses overlapped I/O to perform reads from the file. Data read from the file is provided in a 'push fashion' via the CAsyncFileReader::Callback interface.

Public Member Functions
	CAsyncFileReader (const JetByteTools::Win32::_tstring &filename, Callback &callback, IIOPool &pool, IAllocateBuffers &allocator)
	Read the specified file asynchronously using overlapped I/O via the threads in the supplied IIOPool into buffers provided by the IAllocateBuffers instance and push the data that is read to the CAsyncFileReader::Callback interface.
	~CAsyncFileReader ()
virtual HANDLE	GetWaitHandle () const
	Access a HANDLE to wait on by passing it to one of the Wait Functions.
virtual void	Wait () const
	Wait indefinitely for the object to become signalled.
virtual bool	Wait (const Milliseconds timeout) const
	Wait, with a time limit, for the object to become signalled.
Static Public Member Functions
static void	Wait (HANDLE handle)
	Wait indefinitely for the supplied handle to become signalled.
static bool	Wait (HANDLE handle, const Milliseconds timeout)
	Wait, with a time limit, for the supplied handle to become signalled.
Classes
class	Callback
	An interface for users of the CAsyncFileReader to be notified of the results of the asynchronous read operations on the file. More...
