The resources a task uses to perform the specified operation are acquired exclusively when the task transitions from the Verified state to the Reserved state. These resources can be clocks or channels on a device, trigger lines on a PXI chassis, or buffer memory in the computer. Reserving these resources prevents other tasks from using these resources, which interferes with this task performing the specified operation. You can explicitly perform this transition by calling the Control Task function/VI with Action set to Reserve. This transition fails if some task resources are currently reserved by another task. If the task can gain access to all the resources it uses, the task is successfully reserved and transitions to the Reserved state. Otherwise, it remains in the Verified state.
