AddPenInputHRC
2.0
Adds pen data to an HRC object for recognition. A recognizer must export this function.
int AddPenInputHRC( HRC hrc, LPPOINT lppt, LPVOID lpvOem, UINT fuOem, LPSTROKEINFO lpsi )
Parameters
hrc
Handle to the HRC object.
lppt
Address of an array of POINT structures.
lpvOem
Address of a buffer containing OEM data, or NULL if there is no OEM data.
fuOem
Flags to specify which OEM data is valid.
lpsi
Address of a STROKEINFO structure.
Return Value
Returns HRCR_OK if successful; otherwise, returns one of the following
negative values:
Constant
| Description
| HRCR_ERROR
| Invalid parameter or other error.
| HRCR_MEMERR
| Insufficient memory.
|
Comments
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 AddPenInputHRC. This means that the HPENDATA object that the recognizer returns through its CreatePenDataHRC function may differ from hpndt in its OEM data.
