taskpolicy(8) BSD System Manager's Manual taskpolicy(8)
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
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 manor as -d.
-b Run the program after calling setpriority(2) with a priority of PRIO_DARWIN_BG.
