L_INT pEXT_CALLBACK YourFunction(nZoneIndex, pszWord, pVerify, pUserData)

L_INT nZoneIndex;	/* zone index */

pszWord	Character string that contains the suggested word for the recognized word.
pVerify	Pointer to be updated with user verification answer for the suggested word.
pUserData	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 ZONEDATA structure.)

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
