SetAlphabetPriorityHRC

2.0

Specifies the priority of alphabet sets in an HRC object.

int SetAlphabetPriorityHRC( HRC hrc, ALC alc, LPBYTE rgbfalc )

Parameters

hrc

Handle to the HRC object.

alc

Alphabet priority. This value is one or more ALC_ values combined using the bitwise-OR operator.

rgbfalc

Address of a 256-bit (32-byte) buffer whose bits map to ANSI single-byte characters if alc contains ALC_USEBITMAP; otherwise, it can be NULL.

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.
HRCR_UNSUPPORTED	The recognizer does not support this function.

Comments

Some recognizers may not support ALC_ values and priorities. An application should check for HRCR_UNSUPPORTED when using this function.

For a description of how a recognizer uses alphabet priority, see Configuring the HRC in Chapter 5, The Recognition Process. For a list of alphabet codes, see Chapter 13, Pen Application Programming Interface Constants.
