mach/task_policy.h

These are the calls for accessing the policy parameters of a particular task. The extra 'get_default' parameter to the second call is IN/OUT as follows: 1) if asserted on the way in it indicates that the default values should be returned, not the ones currently set, in this case 'get_default' will always be asserted on return; 2) if unasserted on the way in, the current settings are desired and if still unasserted on return, then the info returned reflects the current settings, otherwise if 'get_default' returns asserted, it means that there are no current settings due to other parameters taking precedence, and the default ones are being returned instead.
