Introduction and questions

Hi!
My name is Ignacio and I'm a Junior Telecommunications Engineer from 
Spain.
i'm currently working as investigator and I'm developing a measurement 
system based on Comedilib and USB-DUXfast.
I've achieved some results using programs such as qtscope and 
Ktimetrace but I'd like to be able to develop something that fits 
better my needs.
I need USB-DUXfast to start acquiring using an external trigger and 
acquire about 10000 samples at a selectable frequency (between 200KHz 
and 3MHz) and save all this data in a file.

I've been experimenting programming and I'm able to acquire and save 
data but the trigger subject is still resisting.
I think I need to program a command that does that for me but there are 
several hints I don't know how to solve.
-> Read function -> I can't find documentation for it. I've seen in 
several examples the use of write function and the advice of using read 
function but I can't find information about it.
->Trigger input in USB-DUXfast -> Can I use any channel as trigger 
input and just select it in start_arg or should I uses the external 
trigger input in the board but then, which is the value of start_arg I 
should use?.

By now, if anyone can solve this questions or has any advice for me, I 
would be really pleased, thanks for your time,

Ignacio
