<method name="wait_for_task_completion">
<return type="void" />
<return type="int" enum="Error" />
<param index="0" name="task_id" type="int" />
<description>
Pauses the thread that calls this method until the task with the given ID is completed.
Returns [constant @GlobalScope.OK] if the task could be successfully awaited.
Returns [constant @GlobalScope.ERR_INVALID_PARAMETER] if a task with the passed ID does not exist (maybe because it was already awaited and disposed of).
Returns [constant @GlobalScope.ERR_BUSY] if the call is made from another running task and, due to task scheduling, the task to await is at a lower level in the call stack and therefore can't progress. This is an advanced situation that should only matter when some tasks depend on others.
