NAME
IND_ADDHANDLER -- Add an input handler to the device
FUNCTION
Add a function to the list of functions called to handle
input events generated by this device. The function is called
as
newInputEvents = Handler(inputEvents, handlerData);
D0 A0 A1
IO REQUEST
io_Message mn_ReplyPort set
io_Device preset by OpenDevice
io_Unit preset by OpenDevice
io_Command IND_ADDHANDLER
io_Data a pointer to an interrupt structure.
is_Data the handlerData pointer described above
is_Code the Handler function address
NOTES
The interrupt structure is kept by the input device until a
RemHandler command is satisfied for it.
input.device/IND_REMHANDLER input.device/IND_REMHANDLER
NAME
IND_REMHANDLER -- Remove an input handler from the device
FUNCTION
Remove a function previously added to the list of handler
functions.
IO REQUEST
io_Message mn_ReplyPort set
io_Device preset by OpenDevice
io_Unit preset by OpenDevice
io_Command IND_REMHANDLER
io_Data a pointer to the interrupt structure.
NOTES
This command is not immediate
input.device/IND_SETMPORT input.device/IND_SETMPORT
NAME
IND_SETMPORT -- Set the current mouse port
FUNCTION
This command sets the gameport port at which the mouse is
connected.
IO REQUEST
io_Message mn_ReplyPort set if quick I/O is not possible
io_Device preset by the call to OpenDevice
io_Unit preset by the call to OpenDevice
io_Command IND_SETMPORT
io_Flags IOB_QUICK set if quick I/O is possible
io_Length 1
io_Data a pointer to a byte that is either 0 or 1,
indicating that mouse input should be obtained
from either the left or right controller port,
respectively.
input.device/IND_SETMTRIG input.device/IND_SETMTRIG
NAME
IND_SETMTRIG -- Set the conditions for a mouse port report
FUNCTION
This command sets what conditions must be met by a mouse
before a pending Read request will be satisfied. The trigger
specification is that used by the gameport device.
IO REQUEST
io_Message mn_ReplyPort set if quick I/O is not possible
io_Device preset by the call to OpenDevice
io_Unit preset by the call to OpenDevice
io_Command IND_SETMTRIG
io_Flags IOB_QUICK set if quick I/O is possible
io_Length sizeof(gameportTrigger)
io_Data a structure of type GameportTrigger, which
has the following elements
gpt_Keys -
GPTB_DOWNKEYS set if button down transitions
trigger a report, and GPTB_UPKEYS set if button up
transitions trigger a report
gpt_Timeout -
a time which, if exceeded, triggers a report;
measured in vertical blank units (60/sec)
gpt_XDelta -
a distance in x which, if exceeded, triggers a
report
gpt_YDelta -
a distance in x which, if exceeded, triggers a
report
input.device/IND_SETMTYPE input.device/IND_SETMTYPE
NAME
IND_SETMTYPE -- Set the current mouse port controller type
FUNCTION
This command sets the type of device at the mouse port, so
the signals at the port may be properly interpreted.
IO REQUEST
io_Message mn_ReplyPort set if quick I/O is not possible
io_Device preset by the call to OpenDevice
io_Unit preset by the call to OpenDevice
io_Command IND_SETMTYPE
io_Flags IOB_QUICK set if quick I/O is possible
io_Length 1
io_Data the address of the byte variable describing
the controller type, as per the equates in
the gameport include file
input.device/IND_SETPERIOD input.device/IND_SETPERIOD
NAME
IND_SETPERIOD -- Set the key repeat period
FUNCTION
This command sets the period at which a repeating key repeats.
This command always executes immediately.
IO REQUEST - a timerequest
tr_node.io_message mn_replyport set if quick i/o is not possible
tr_node.io_device preset by the call to opendevice
tr_node.io_unit preset by the call to opendevice
tr_node.io_command ind_setperiod
tr_node.io_flags iob_quick set if quick i/o is possible
tr_time.tv_secs the repeat period seconds
tr_time.tv_micro the repeat period microseconds
input.device/IND_SETTHRESH input.device/IND_SETTHRESH
NAME
IND_SETTHRESH -- Set the key repeat threshold
FUNCTION
This command sets the time that a key must be held down before
it can repeat. The repeatability of a key may be restricted
(as, for example, are the shift keys).
This command always executes immediately.
IO REQUEST - a timerequest
tr_node.io_message mn_replyport set if quick i/o is not possible
tr_node.io_device preset by the call to opendevice
tr_node.io_unit preset by the call to opendevice
tr_node.io_command ind_setthresh
tr_node.io_flags iob_quick set if quick i/o is possible
tr_time.tv_secs the threshold seconds
tr_time.tv_micro the threshold microseconds
input.device/IND_WRITEEVENT input.device/IND_WRITEEVENT
NAME
IND_WRITEEVENT -- Propagate an input event to all handlers
FUNCTION
IO REQUEST
io_Message mn_ReplyPort set if quick I/O is not possible
io_Device preset by the call to OpenDevice
io_Unit preset by the call to OpenDevice
io_Command IND_WRITEEVENT
io_Flags IOB_QUICK set if quick I/O is possible
io_Length should be sizeof(struct InputEvent)
io_Data a pointer to the struct InputEvent:
ie_NextEvent
will be ignored.
ie_Class
ie_SubClass
ie_Code
ie_Qualifier
ie_X, ie_Y
as desired
ie_TimeStamp
will be set by this call (V36)
NOTES
The contents of the input event are destroyed.
This function was documented in V34 and earlier to allow
chaining of events via ie_NextEvent. The implementation
never allowed that. The documentation now reflects this.
ie_TimeStamp is set only in V36 and later. Software written
to run on earlier versions should set this field to the
current time.
input.device/PeekQualifier input.device/PeekQualifier
NAME
PeekQualifier -- get the input device's current qualifiers (V36)
SYNOPSIS
qualifier = PeekQualifier()
d0
UWORD PeekQualifier( VOID );
FUNCTION
This function takes a snapshot of what the input device thinks
the current qualifiers are.
RESULTS
qualifier - a word with the following bits set according to
what the input device knows their state to be:
IEQUALIFIER_LSHIFT, IEQUALIFIER_RSHIFT,
IEQUALIFIER_CAPSLOCK, IEQUALIFIER_CONTROL,
IEQUALIFIER_LALT, IEQUALIFIER_RALT,
IEQUALIFIER_LCOMMAND, IEQUALIFIER_RCOMMAND,
IEQUALIFIER_LEFTBUTTON, IEQUALIFIER_RBUTTON,
IEQUALIFIER_MIDBUTTON
NOTE
This function is new for V36.
