NAME    [Toc]    [Back]

       personality - set the process execution domain

SYNOPSIS    [Toc]    [Back]

       int personality(unsigned long persona);

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       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    [Toc]    [Back]

       EINVAL persona does not refer to a valid execution domain.

FILES    [Toc]    [Back]

       /usr/include/linux/personality.h

CONFORMING TO    [Toc]    [Back]

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