L_INT pEXT_CALLBACK YourFunction(nZoneIndex, pszWord, pVerify, pUserData)
Reports the suggested word for the last recognized word in a specific zone.
Index of the zone containing the recognized word.
Character string containing the suggested word for the recognized word.
Pointer to be updated with user's verification answer for the suggested word.
A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData member of a ZONEDATA2 structure.)
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
VERIFICATIONCALLBACK2 reports the suggested word for a recognized word in a zone.
VERIFICATIONCALLBACK2 is called during the recognition process.
To enable VERIFICATIONCALLBACK2, call the L_Doc2AddZone / L_Doc2AddZoneExt function or the L_Doc2UpdateZone / L_Doc2UpdateZoneExt function, and pass your callback function in the pfnCallback member of the ZONEDATA2 structure.
When calling the L_Doc2Recognize / L_Doc2RecognizeExt function, set the bEnableSubSystem and bEnableCorrection members of the RECOGNIZEOPTS2 structures to TRUE.
