aiolkinit(ADM) 19 June 1992 aiolkinit(ADM) Name aiolkinit - set up AIO memory locking permissions Syntax /etc/aiolkinit [raw-device] Description The aiolkinit utility allows a system administrator to control which users may lock memory for AIO use, and how much can be locked. This utility reads the /usr/lib/aiomemlock file, and sets up an internal ker- nel table entry for each line. Typically, aiolkinit is not invoked directly, but is called by a script in the /etc/rc2.d directory. Note that this script should be invoked before starting up any program that uses AIO. Invoking aiolkinit after boot causes entries that have been added to /usr/lib/aiomemlock to be revised. Removing entries does not affect their memory locking ability until reboot. The aiolkinit program defaults to opening /dev/rroot to call the appropriate AIO I/O control command (ioctl). If /dev/rroot does not support AIO, an alternate AIO device must be provided as an argument. Notes This command can be run only by the super user.
