[PD] Structures: get data dynamically

[raul diaz]

Hi list!

I'm taking a look at data structures.
In the attached patch I'm trying to select an init point and an end point
for a sample using an "init struct" and an "end struct".
I can select this init and end point with the mouse but then, I would like
to use this init and end point information for audio process.
I can obtain the init point or end point value by means of pointer & get,
but I would like to obtain this value dynamically, that means, to obtain the
value each time I change the init or end point.
How can I obtain this values dynamically? Somebody has any suggestion?
Thanks and regards!

Ciao.
