set up asynchronous I/O memory locking permissions
The aiolkinit utility
allows a system administrator to control which users
may lock memory for AIO use, and how much memory can be locked.
This utility reads the
/usr/lib/aiomemlock file, and sets up
an internal kernel 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.
This command can be run only by the super user.
