[Playerstage-users] question about MessageQueue::Wait()

[Marco T. <mar...@li...>]

Hello,
   i am new to player and i am trying to write a driver that requires a
position2d and a laser interface. Before performing calculations i want to
be sure that i received some data from the laser. How can i handle this
problem?

At the moment i subscribe both the position and laser device to the InQueue
of my Driver but in this way the Wait function blocks the thread until it
receives a message from any of the interface subscribed, while i would like
to block until i receive a message from the laser.

Thank you for the help!

Greetings

Marco
