NAME
     taskpolicy — execute a program with an altered I/O or scheduling policy

SYNOPSIS
     taskpolicy [-d policy] [-b] program [arg1 [...]]

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 chil‐
     dren 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 argu‐
		      ment can either be an integer, or a symbolic string like
		      "default" or "throttle", which is interpreted case-
		      insensitively.

	   -g policy  Run the program after calling setiopolicy_np(3) with an
		      iotype of IOPOL_TYPE_DISK, a scope of IOPOL_SCOPE_DAR‐
		      WIN_BG, and the specified policy. The argument is inter‐
		      preted in the same manor as -d.

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