GetChecksumParameters Method (position, chkType, start, size, crcSize, crcPolynomial, crcInitialValue, crcFinalXOR, crcReverseData, crcReflection)

Gets the current checksum parameters. Media must be selected before using this method.

Parameters

position ( Int32 %): Checksum position.

chkType ( Checksum %): Checksum type.

start ( Int32 %): Zero indexed starting point of position, where checksum count is started.

size ( Int32 %): Determines, how many bytes are counted for checksum.

crcSize ( Int32 %): The size of the CRC (Cyclic Redundancy Check) checksum, given in bits.

crcPolynomial ( Int32 %): The polynom of the CRC (Cyclic Redundancy Check) checksum.

crcInitialValue ( Int32 %): The initial value of the CRC (Cyclic Redundancy Check) checksum.

crcFinalXOR ( Int32 %): The integer on which, with the calculated CRC (Cyclic Redundancy Check) checksum, the XOR operation is done, at the end.

crcReverseData ( Boolean %): If True, the calculated CRC (Cyclic Redundancy Check) checksum is reversed at the end.

crcReflection ( Boolean %): If True, bits of the calculated CRC (Cyclic Redundancy Check) checksum, are swapped around its centre.

Remarks

Parameters CRCSize, CRCPolynomial, CRCInitialValue, CRCFinalXOR, CRCReverseData and/or CRCReflection can be used only, when checksum type is Custom (GX_CHK_CUSTOM).
