PERSONALITY(2)

NAME
       personality - set the process execution domain

SYNOPSIS
       int personality(unsigned long persona);

DESCRIPTION
       Linux  supports different execution domains, or personali-
       ties, 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  pro-
       vide  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 appropriately.

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

FILES

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