Coppy Buffer OF Stochastic ?
surubabs:
What is Main, what is Signal ? CopyBuffer need 5 parameters.
Dear friend i am little confused how to coppy buffer of stochastic ?
Please correct this for me,,
Thanks in a advance

You post your code but don't correct it, why ?
Stochastic main signal stants for main, Signal stants for signal line,

I saw your code. Do you understand what I wrote ? CopyBuffer need 5 parameters. You have only 4.

No i dont understand, but i could find a code like this in some other code base, but i dont know how to use it.

How many data do you want to copy ? It's "amount" or instead "count".No i dont understand, but i could find a code like this in some other code base, but i dont know how to use it.

Only Main signal value and Signal line value i need,
