Note: As with all other HHP structures, the dwStructSize member of the structure must be set before calling this function. (Set
to sizeof (HHP_IMAGER_CAPS).)
Syntax hhpReadImagerCapabilities
(
HHP_IMAGER_CAPS pImgrCaps
)
Parameter Description
pImgrCaps Pointer to the HHP_IMAGER_CAPS structure.
hhpReadSymbologyConfig
Reads configuration items for a single symbology or for all symbologies. Individual items to be read are specified by adding the
appropriate mask bit (OR it) to the mask member of the structure to which it belongs. Only items whose bits are set are read; all
other items are ignored.
Syntax hhpReadSymbologyConfig
(
SetupType_t cfgType,
int nSymbol,
PVOID pvSymStruct
)
Parameter Description
cfgType Use SETUP_TYPE_CURRENT for the current settings, or SETUP_TYPE_DEFAULT for the
customer default settings.
nSymbol One of the symbology enumerated types, e.g., SYM_CODE39, SYM_OCR, or SYM_ALL to read all
symbologies.
pStruct Pointer to the appropriate structure based on nSymbol, e.g., CODE39_T, OCR_T, or
HHP_SYM_CONFIG if all symbologies.
hhpReadSymbologyRangeMaxMin
Returns the specified symbology range maximum and minimum values. If a symbology has no range values, the function returns
-1 for the minimum and maximum values.
Syntax hhpReadSymbologyRangeMaxMin
(
int symbol,
PLONG pnRangeMin,
PLONG pnRangeMax
)
Parameter Description
int The enumerated symbology types, eg., SYM_CODE39, SYM_PDF417, or SYM_ALL to read the
max/min range for all symbologies.
pnRangeMin A LONG pointer to hold the minimum range value for single symbologies, or a LONG array of size
NUM_SYMBOLOGIES if SYM_ALL specified. The min value will be -1 if the symbology does not
support a minimum length value.
pnRangeMax A LONG pointer to hold the maximum range value for single symbologies, or a LONG array of size
NUM_SYMBOLOGIES if SYM_ALL specified. The max value will be -1 if the symbology does not
support a maximum length value.
