NAME

     taskpolicy -- execute a program with an altered I/O or scheduling policy or change settings of already running process

SYNOPSIS

     taskpolicy [-d policy] [-g policy] [-c clamp] [-b] [-t thruput_tier] [-l latency_tier] [-a] program [arg1 [...]]
     taskpolicy [-b|-B] [-t thruput_tier] [-l latency_tier] [-p pid]

DESCRIPTION

     The taskpolicy program uses the setiopolicy_np(3) and setpriority(2) APIs to execute a program with altered I/O or scheduling policies. All
     children of the specified program also inherit these policies.

     taskpolicy accepts the following flags and arguments:

	   -d policy  Run the program after calling setiopolicy_np(3) with an iotype of IOPOL_TYPE_DISK, a scope of IOPOL_SCOPE_PROCESS, and the
		      specified policy. The argument can either be an integer, or a symbolic string like "default" or "throttle", which is inter-
		      preted case-insensitively.

	   -g policy  Run the program after calling setiopolicy_np(3) with an iotype of IOPOL_TYPE_DISK, a scope of IOPOL_SCOPE_DARWIN_BG, and the
		      specified policy. The argument is interpreted in the same manner as -d.

	   -c clamp   Run the program using the specified QoS clamp. The argument can be either "utility", "background", or "maintenance", which
		      is interpreted case-insensitively.

	   -p pid     Change settings for the process specified by pid.

	   -b	      Run the program after calling setpriority(2) with a priority of PRIO_DARWIN_BG.

	   -B	      Move target process out of PRIO_DARWIN_BG.

	   -t	      Set throughput tier of the process to thruput_tier.

	   -l	      Set latency tier of the process to latency_tier.

	   -a	      Run the program with the resource management policies given to applications.
