_maintRequest
Synchronous implementation of addEventSource and removeEventSource functions.
Declaration
virtual IOReturn _maintRequest(
void *command,
void *data,
void *,
void *);Return Value
kIOReturnUnsupported if the command given is not implemented, kIOReturnSuccess otherwise.
Overview
This function implements the commands as defined in the maintCommandEnum. It can be subclassed but it isn't an external API in the usual sense. A subclass implementation of _maintRequest would be called synchronously with respect to the work loop and it should be implemented in the usual way that an ioctl would be.
