FCRC16_Final
long FCRC16_Final( [in, out]long* pCRC
);
Return value
The checksum.
Parameters
pCRC
[in/out] The
crc variable.
Remarks
Call this function to retrieve the
checksum from the
crc variable
specified by pCRC.
After the FCRC16_Final function is performed, the
crc variable
is initialized for new calculations, as it would be called
FCRC16_Init
again.
Note. Before the first call to
FCRC16_Update,
FCRC16_UpdateStr or
FCRC16_Final functions, the
crc variable
must be initialized with
FCRC16_Init.
VB Example
Private Sub MyButton_Click()
Dim strdata As String
strdata = "Hello World!"
Dim strlength As Long
strlength = Len(strdata)
'Convert the string to byte array
Dim bindata() As Byte
ReDim bindata(1 To strlength)
For i = 1 To strlength
bindata(i) = Asc(Mid(strdata, i, 1))
Next i
'Initialize the crc variable to store intermediate results between function calls
Dim crcvar As Long
FCRC16_Init crcvar
'Update the crc variable with first part
Dim firstpart As Long
firstpart = strlength / 3
FCRC16_Update crcvar, bindata(1), firstpart
'Update the crc variable with second part
FCRC16_Update crcvar, bindata(firstpart + 1), strlength - firstpart
'Get the checksum
Dim checksum As Long
checksum = FCRC16_Final(crcvar)
'Show the hexadecimal representation of the checksum
MsgBox FCRC_LongToHex16(checksum, True)
End Sub
