Member Function Documentation

bool PPort::commit

(

)

set the bits off the // port according to previous call to setBit().

Definition at line 62 of file PPort.cpp.

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.

Definition at line 104 of file PPort.cpp.

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.

Definition at line 86 of file PPort.cpp.

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.

Definition at line 72 of file PPort.cpp.

bool PPort::setPort

(

int

ioPort

)

set the ioport associated to the // port.

Returns:

true if the binding was possible

Definition at line 48 of file PPort.cpp.

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.

Definition at line 95 of file PPort.cpp.
