The

OnDigEventVDM

command sets the address of a “C”-style (

__stdcall

) function to be called when a

digital match event occurs. This function uses a similar mechanism as the

OnEventVDM

command. The

prototype of the callback function for

OnDigEventVDM

is:

void DigEventFunc( DevHandleT devHandle, LPARAM lParam )

The

lParam

value that is passed to

OnDigEventVDM

is passed on to the callback function when the event

occurs. For details, see the description of

OnEventVDM

Note: This function sets the event generation mechanism to be a callback function, replacing any

previously defined event notification mechanism. Only one event notification mechanism

can be used at one time.
