OK, this is called the "

XY problem".

You are asking for information on what you

think to be the way to approach your problem, The problem

is, this is not necessarily the proper way to approach it, and solutions to the question you first posed may not be a useful or efficient way to

actually address your real need.

So you need to explain

why you think you want to do this. It may be easier than you think, it may even not be necessary, and in particular, the answers you have otherwise received

may even be quite inappropriate.
