[Playerstage-users] Doubt about reading from laser

[Cesar F. <da...@gm...>]

Greetings,

I need to make sequencial readings of the ranges given by a laser. The
command playerc_read does garantee that if it is called several times
within a loop, all the values in all the readings will present new
data? What I mean is: if I call 5 times (for example) the read
function within a loop (without any sort of sleep) is there any chance
it returns to me the same ranges that it returned at the previous call
of the function read, simply because the server could not acquire new
data from the robot, or it will ask the robot for new data and will
present it to me?

If it could repeat data, suggestions about how to garantee that I only
receive new data will be really appreciated

Thank you
Cesar
