Workaround for the deprecated Crypt2.CrcBytes method

Shows how to replace the deprecated CrcBytes method. (Chilkat is moving away from the use of CkByteData.) C

#include <C_CkCrypt2.h>
#include <C_CkByteData.h>
#include <C_CkBinData.h>

void ChilkatSample(void)
    {
    HCkCrypt2 crypt;
    const char *path;
    const char *algorithm;
    HCkByteData inData;
    unsigned long crc;
    HCkBinData bdIn;

    crypt = CkCrypt2_Create();

    path = "c:/someDir/example.dat";
    algorithm = "crc-32";

    //  ------------------------------------------------------------------------
    //  The CrcBytes method is deprecated:

    inData = CkByteData_Create();
    CkByteData_loadFile(inData,path);

    crc = CkCrypt2_CrcBytes(crypt,algorithm,inData);

    //  ------------------------------------------------------------------------
    //  Workaround.
    //  (Chilkat is moving away from using CkByteData)

    bdIn = CkBinData_Create();
    CkBinData_LoadFile(bdIn,path);

    crc = CkCrypt2_CrcBd(crypt,algorithm,bdIn);


    CkCrypt2_Dispose(crypt);
    CkByteData_Dispose(inData);
    CkBinData_Dispose(bdIn);

    }
