Comments
Before terminating, the application must free the pen data, using
DestroyPenData. Because the recognizer copies any data it requires, the recognizer does not
affect the original data.
Calling this function is equivalent to adding data to the recognition context
by walking the pen data strokes from beginning to end in stroke order. (Note
that the stroke order may not necessarily be in chronological order if insertions
have been made.)
A recognizer is not required to use or maintain OEM data; that is, a
recognizer may choose to ignore some or all of the OEM data it receives from
AddPenDataHRC. This means that the
HPENDATA object that the recognizer returns through its
CreatePenDataHRC function may differ from
hpndt in its OEM data.
