Detailed Description

A device wrapping a BeOS IO Object.

This class wraps one the DataIO family of classes provided by BeOS, thereby allowing these classes to be used as devices.

Constructor & Destructor Documentation

BeOSDevice() [1/3]

wfio::os::beos::BeOSDevice::BeOSDevice ( BDataIO *  io, int *  error = NULL  )

inline

Construct a new BEOSDevice from a BDataIO.

Parameters

fd	The BDataIO to wrap.
error	An optional error indicator.

BeOSDevice() [2/3]

wfio::os::beos::BeOSDevice::BeOSDevice ( BPositionIO *  io, int *  error = NULL  )

inline

Construct a new BEOSDevice from a BPositionIO.

Parameters

fd	The BPositionIO to wrap.
error	An optional error indicator.

BeOSDevice() [3/3]

wfio::os::beos::BeOSDevice::BeOSDevice ( BBufferIO *  io, int *  error = NULL  )

inline

Construct a new BEOSDevice from a BDataIO.

Parameters

fd	The BBufferIO to wrap.
error	An optional error indicator.
