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.
