| 19 | program uses the\r | |
| 20 | .Xr setiopolicy_np 3\r | |
| 21 | and\r | |
| 22 | .Xr setpriority 2\r | |
| 23 | APIs to execute a program with altered I/O or scheduling policies. All\r | |
| 24 | children of the specified program also inherit these policies.\r | |
| 25 | .Pp\r | |
| 26 | .Nm\r | |
| 27 | accepts the following flags and arguments:\r | |
| 28 | .Bl -tag -width "d policy " -offset indent\r | |

| 30 | Run the program after calling\r | |
| 31 | .Xr setiopolicy_np 3\r | |
| 32 | with an iotype of IOPOL_TYPE_DISK, a scope of IOPOL_SCOPE_PROCESS, and the\r | |
| 33 | specified policy. The argument can either be an integer, or a symbolic string\r | |
| 34 | like "default" or "throttle", which is interpreted case-insensitively.\r | |
