padGet
Receives new data from the pad by checking for and returning the last horizontal/vertical coordinates and pen status. A pen
status of 1 indicates the continuation of a line (lineto(x,y )), whereas a 0 represents the beginning of a stroke (moveto(x,y)).
NULL pointers may be passed as any of the parameters to suppress gathering of the associated data. Note that if no pen
activity occurred since the last padUpdate, the function returns FALSE and does not alter the values pointed to.
Syntax
BOOL padGet (
int *XPosition,
int *YPosition,
int *Pen
)
Parameter
XPosition
YPosition
Pen
Returns
Returns TRUE if new pen data was received, FALSE otherwise.

padGetAllMagCardTracks
Returns data captured from all tracks on a magnetic card, if available. A card must have been swiped prior to executing this
command, otherwise it returns zero. The TrackXSize parameters should contain the maximum buffer sizes for each track
before the call, and after will contain actual track sizes after the call. The card reader must be reset using padResetMagCard
before calling this command. Refer to page 5-1 for sample code that describes how to read the MSR.
Syntax
BOOL padGetAllMagCardTracks(
BYTE *Tracks,
char *Track1,
WORD *Track1Size,
char *Track2,
WORD *Track2Size,
char *Track3,
WORD *Track3Size
)
Parameter
Tracks
Track1
Track1Size
Track2
Track2Size
Track3
Track3Size
Returns
Returns TRUE if the function call succeeds, FALSE otherwise.
