D.2.12.2 killTask

Usage:

killTask(t), t task

Return:

nothing. If the state of t is 'started', then t is stopped first. The internal data structures of t are erased and its state is set to 'uninitialized'.

Note:

'killTask(t);' is not the same as 'kill t;'. The latter command does not erase the internal data structures of t. Hence killTask() should be called for any no longer needed task in order to free memory.
