_LANGUAGE_ example to base-64 encode and decode a string. C

#include <C_CkBinData.h>

void ChilkatSample(void)

    BOOL success;

    const char *s;
    const char *strBase64;

    success = FALSE;

    bd = CkBinData_Create();

    s = "A friend called me up the other day and talked about investing in a dot-com that sells lobsters. Internet lobsters. Where will this end? --Donald Trump";

    success = CkBinData_AppendString(bd,s,"utf-8");

    strBase64 = CkBinData_getEncoded(bd,"base64");
    printf("%s\n",strBase64);

    // To decode:
    bd2 = CkBinData_Create();
    CkBinData_AppendEncoded(bd2,strBase64,"base64");

    decoded = CkBinData_getString(bd2,"utf-8");
    printf("%s\n",decoded);


    CkBinData_Dispose(bd);
    CkBinData_Dispose(bd2);
