PERSONALITY(2)		  Linux Programmer’s Manual	       PERSONALITY(2)



NAME
       personality - set the process execution domain

SYNOPSIS
       #include <sys/personality.h>

       extern 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.

       This  function will return the current personality when persona equals
       0xffffffff. Otherwise, it will make the execution domain referenced by
       persona the new execution domain of the current process.

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.
