Name
       uac - Unaligned Access Message Control

Syntax
       uac [s] [p] value

Description
       The  command  controls  the  printing of "Fixed up unaligned data access for pid nnn at pc 0xAddr" messages.  The command is used to set or
       display the flag that controls printing the message for the system or for the parent process of the user, which is typically a shell.

       If value is present, the flag is set; otherwise, the current flag setting is displayed.	The value can be either a zero	(0),  which  turns
       the  flag  off,	or  a  one  (1), which turns the flag on.  If both the system and the user flags are on (set, 1) the unaligned data access
       errors are reported to the user.  If either flag is off (not set, 0), the unaligned data access errors are not reported.

Options
       The following options can be used with the command:

       s    Set/display the current flag setting for the system.

       p    Set/display the current flag setting for the parent process.

Restrictions
       You must be superuser to set the system flag.
