165     @param messageArgument An argument for message, dependent on its type.
166     @param argSize Non zero if the argument represents a struct of that size, used when delivering messages outside the kernel. */
196 The driver class is instantiated and <code>init()</code> called with its property table. The new driver instance is then attached to the provider, and has its @link probe probe@/link method called with the provider as an argument. The default <code>probe</code> method does nothing but return success, but a driver may implement this method to interrogate the provider to make sure it can work with it. It may also modify its probe score at this time. After probe, the driver is detached and the next in the list is considered (ie. attached, probed, and detached).
841     @result <code>true</code> if the property does not exist in the matching table. If the property exists in the matching dictionary but not the IOService property table, failure is returned. Otherwise the result of calling the property from the matching dictionary's <code>isEqualTo</code> method with the IOService property as an argument is returned. */

1098     @param argument An argument defined by the provider family, not used by IOService.

1109     @param messageArgument An argument defined by the provider family, not used by IOService.
1120     @param argument An argument defined by the provider family, not used by IOService.
1121     @param argSize Specifies the size of argument, in bytes.  If argSize is non-zero, argument is treated as a pointer to argSize bytes of data.  If argSize is 0 (the default), argument is treated as an ordinal and passed by value.

1370     @discussion Call <code>registerInterestedDriver</code> on the IOService object you are interested in receiving power state messages from, and pass a pointer to the interested driver (<code>this</code>) as an argument.
1467     If the driver is managing the idleness determination totally on its own, the value of the <code>type</code> parameter should be <code>kIOPMSubclassPolicy</code>, and the driver should override the <code>activityTickle</code> method. The superclass IOService implementation of <code>activityTickle</code> does nothing with the <code>kIOPMSubclassPolicy</code> argument.
