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



NAME
       personality - set the process execution domain

SYNOPSIS
       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.

       personality  will  make  the execution domain referenced by persona the
       new execution domain of the current process.

RETURN VALUE
       On success, persona is made the new execution domain and  the  previous
       persona  is returned. On error, -1 is returned, and errno is set appro-
       priately.

ERRORS
       EINVAL persona does not refer to a valid execution domain.


FILES
       /usr/include/linux/personality.h

CONFORMING TO
       personality is Linux-specific  and  should  not  be  used  in  programs
       intended to be portable.
