PPort * PPort::getPPort

(

int

ioPort

)

[static]

return the PPort object associated to the given IO port.

if no PPort is already associated to the port, one is created

bool PPort::setBit	(	const void *	ID,
		int	bit,
		bool	stat
	)

set a data bit of the // port.

Returns:

false if IO port not set, or bit not registered by ID.

Parameters:

	ID	the identifier used to register the bit
	stat	the stat wanted for the given bit
	bit	the bit to set. They are numbered from 0 to 7.

bool PPort::registerBit	(	const void *	ID,
		int	bit
	)

register a bit for object ID.

Parameters:

	ID	the identifier used to register the bit it should be the 'this' pointer.
	bit	the bit of the // port to register

Returns:

false if the bit is allready register with an other ID, or if the // port is not initialised.

bool PPort::unregisterBit	(	const void *	ID,
		int	bit
	)

release a bit.

Parameters:

	ID	the identifier used to register the bit
	bit	the bit to register.

Returns:

false if the bit was not registered by ID or if the if the // port is not initialised.

bool PPort::isRegisterBit	(	const void *	ID,
		int	bit
	)			const

test if a bit is registerd.

Parameters:

	ID	the identifier used to register the bit
	bit	the bit to test.

Returns:

false if the bit was not registered by ID or if the if the // port is not initialised.
