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



NAME
       personality - set(7,n,1 builtins) the process execution domain

SYNOPSIS
       long 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(2,7)  numbers into signal(2,7) 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(8,n), -1 is returned,
       and errno is set(7,n,1 builtins) appropriately.

ERRORS
       EINVAL The kernel was unable to change the personality.


FILES
       /usr/include/linux/personality.h

CONFORMING TO
       personality is Linux-specific  and  should  not  be  used  in(1,8)  programs
       intended to be portable.
