Binary data from external

[Dar Scott]

My external C code boilerplate includes a function to create a hex returnable value.  I sometimes do that.  If you learn of a better way, I would like to learn of that.

It is easer with iOS externals.

You might be able to do this by analysis.  If you know your characters will never include a zero byte, then you can just to an ordinary return of data.
