GetAlphabetHRC

Retrieves the alphabet being used in a handwriting recognition context HRC.

int GetAlphabetHRC( HRC hrc, LPALC lpalc, LPBYTE rgbfAlc )

Parameters
hrc

Handle to the HRC object.

lpalc

Address of a buffer that receives the current ALC_ values. If NULL, this parameter is ignored.

rgbfAlc

Address of an array of bits or NULL. If NULL, this parameter is ignored. If lpalc contains ALC_USEBITMAP and rgbfAlc points to a valid array, the array is filled according to the bits set by the SetAlphabetHRC function.

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
If rgbfAlc is not NULL, the array it points to must be large enough to accommodate 256 bits (32 bytes). If the nth bit is set, the nth ANSI character is recognizable. Bits representing characters with ASCII values less than 32 (the space character) currently have no meaning.

ALC_DEFAULT specifies the set of characters at or above ALC_SYSMINIMUM that the recognizer can accurately distinguish.

For a description of alphabets and their relationship to a recognizer, see "Configuring the HRC" in Chapter 5, "The Recognition Process."
