Convert any File to Base64 (and back)

Demonstrates how to get the contents of any file as a base64 string, and then write it back. C

#include <C_CkBinData.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkBinData bd;
    const char *b64Str;
    HCkBinData bd2;

    success = FALSE;

    bd = CkBinData_Create();

    //  This example will load a PDF and return it as a base64 string.
    success = CkBinData_LoadFile(bd,"qa_data/pdf/helloWorld.pdf");
    if (success != TRUE) {
        printf("Failed to load file.\n");
        CkBinData_Dispose(bd);
        return;
    }

    b64Str = CkBinData_getEncoded(bd,"base64");
    printf("%s\n",b64Str);

    //  Now write the base64 string back to the binary PDF file:
    bd2 = CkBinData_Create();
    success = CkBinData_AppendEncoded(bd2,b64Str,"base64");
    success = CkBinData_WriteFile(bd2,"qa_output/helloWorld.pdf");


    CkBinData_Dispose(bd);
    CkBinData_Dispose(bd2);

    }
