How to save a Base64 encoded string to a binary file

For instance, the following XML tag stores the binary data in a Base64
encoded string
<data>TWFuIGlzIGRpc3Rpbmd1aXNoZWQsIG5vdCBvbmx<data>

Any one point to sample code on saving the above string to binary
image (.jpg) file?

base64 class I am using

Tom N wants attention. Don't give it to him.

Just use the base64_decode function on this page and pass it the base64
encoded string, then store the result in a file using the write function
of std::ofstream (opening in binary mode).
