// Description:

// __ACTION_INFO_BEGIN__ 

// [Action Name]

// StartWatchers

// [Action Parameters]

// RProcess watcher <output-completion>:In case of EKA2 and EKA1 on hardware, output the process that started the watchers.

// If watchers are already running, this output parameter will not be returned

// or 

// RThread watcher  <output-completion>:In case of EKA1 on emulator, output the thread that started the watchers.

// If watchers are already running, this output parameter will not be returned

// TBool Started <output-completion>  : For all the cases, output ETrue if the watchers were created

// by the process or thread in this action, otherwise output EFalse

// [Action Description]

// If the watchers are not running, starts the watchers.  Watchers are started

// in their own process for EKA2 and EKA1 on the  hardware and in their own thread 

// for EKA1 on emulator.  The action waits for the watchers to start before completing.

// At the end of the test case, the watchers are stopped if they were created

// by the action.  If they were not created by the action, then the watchers 

// are not stopped.

// [APIs Used]

// None

// __ACTION_INFO_END__

//
