How does my application save the raw data to binary file?

Ok, let's put it simply. I want to save/write to binary file the raw data of each frame in grab acquisition, set file position to end (<- this is for separating frames when I handle the binary file) and avoid lost images. But I am not sure how to play with the buffers. If I set value of 3 (or more) to number of buffers input in IMAQdx Configure Grab.vi (see attachment) I should avoid image losts but in this case, does the IMAQdx Get Image Data.vi save/write one frame at a time (buffer number mode is set to "next") and then run the set file position.vi (my save&grab.vi is inside of a while loop)?

 

Needed procedure:

(configure)->Grab->save one frame->set file position to end->do not lost images->grab new frame->save new frame->...

 

Kudos for any good help!
