PERSONALITY(2) Linux Programmer's Manual PERSONALITY(2)
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 exe-
cution 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/person-
ality.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.
