virtual bool PPCKeyboard::alt ( )

inlinevirtual

Returns: True if alt is currently held.

Definition at line 93 of file kernel/machine/ppc_common/Keyboard.h.

virtual bool PPCKeyboard::capsLock ( )

inlinevirtual

Returns: True if caps lock is currently on.

virtual bool PPCKeyboard::ctrl ( )

inlinevirtual

Returns: True if ctrl is currently held.

Definition at line 85 of file kernel/machine/ppc_common/Keyboard.h.

char PPCKeyboard::getChar ( )

virtual

Retrieves a character from the keyboard. Blocking I/O.

Returns: The character recieved or zero if it is a character without an ascii representation.

Implements Keyboard.

Keyboard::Character PPCKeyboard::getCharacter ( )

virtual

Retrieves a character from the keyboard in special descriptor format. Blocking I/O.

Returns: The character received along with any modifier keys used.

Definition at line 84 of file ppc_common/Keyboard.cc.

References X86Keyboard::getChar().

Keyboard::Character PPCKeyboard::getCharacterNonBlock ( )

virtual

Retrieves a character from the keyboard in special descriptor format. Nonblocking I/O.

Returns: The character recieved along with any modifier keys used. The character can be tested for validity with the CHARACTER_VALID macro.

char PPCKeyboard::getCharNonBlock ( )

virtual

Retrieves a character from the keyboard. Non blocking I/O.

Returns: The character recieved or zero if it is a character without an ascii representation, or zero also if no character was present.

Implements Keyboard.

void PPCKeyboard::initialise ( )

virtual

Initialises the device.

Implements Keyboard.

Definition at line 30 of file ppc_common/Keyboard.cc.

References OpenFirmware::instance().

void PPCKeyboard::setDebugState ( bool enableDebugState )

virtual

Sets the state of the device. When debugging, it is unwise to rely on interrupt- driven I/O, however in normal use polling is extremely slow and CPU-intensive.

The debugger therefore will set the device to "debug state" by calling this function with the argument "true". In "debug state", any buffered input will be discarded, the device's interrupt masked, and the device will rely on polling only. This will be the default state.

When the device is set to "normal state" by calling this function with the argument "false", interrupts may be used, along with buffered input, and it is recommended that during blocking I/O a Semaphore is used to signal incoming interrupts, so that the blocked thread may go to sleep.
