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 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 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 pro-
     grams intended to be portable.
