cGenericDevice Class Reference
[Devices]

cGenericDevice Provides an general interface to communicate with hardware devices. A number of constants define a set of generic commands supported by the cGenericDevice:command method. For each generic command, we describe the data type and information that must be passed by parameter for index and data. command contains of course the command number corresponding to the following list of command constants.

Detailed Description

cGenericDevice Provides an general interface to communicate with hardware devices. A number of constants define a set of generic commands supported by the cGenericDevice:command method. For each generic command, we describe the data type and information that must be passed by parameter for index and data. command contains of course the command number corresponding to the following list of command constants.

Member Function Documentation

bool cGenericDevice::setCallback ( cCallback m_callback  )  [virtual]

Ask the device to call me back periodically.

Ask the device to call me back periodically. If this device supports timed callbacks, this function will return 'true' and will call the supplied m_callback method at haptic rates. If not, this function will return 'false', and you should create your own haptic thread.

Parameters:
m_callback The callback to trigger periodically, or 0 to cancel an existing callback.
Returns:
Returns true if this device supports callbacks, false otherwise.
