NAME
personality - set the process execution domain
SYNOPSIS
#include <sys/personality.h>
int personality(unsigned long persona);
DESCRIPTION
Linux supports different execution domains, or personalities, for each
process.
Among other things, execution domains tell Linux how to map
signal numbers into signal actions.
The execution domain system allows
Linux to provide limited support for binaries compiled under other
UNIX-like operating systems.
If
persona
is not
0xffffffff, then
personality()
sets the caller's execution domain to the value specified by
persona.
Specifying
persona
as 0xffffffff provides a way of retrieving
the current persona without changing it.
A list of the available execution domains can be found in
<sys/personality.h>.
RETURN VALUE
On success, the previous
persona
is returned.
On error, -1 is returned, and
errno
is set appropriately.
ERRORS
- EINVAL
-
The kernel was unable to change the personality.
CONFORMING TO
personality()
is Linux-specific and should not be used in programs intended to
be portable.
