NAME
       setprivexec - allow other processes to exec set-bit programs

SYNOPSIS
       old = setprivexec(onoff)
       int old, onoff;

DESCRIPTION
       If called with a nonzero (zero) argument, the setprivexec() system call
       marks the  process  as  one  that  is  (isn't)  interested  in  holding
       privileged  Mach	 ports of other processes that intend to exec programs
       with set-bit markings (for example, debuggers and  program  launchers).
       A  nonzero  mark persists across exec, but is not inherited by a forked
       child.  The initial value is zero.

       This mark is set to nonzero as a side effect  of	 a  process  making  a
       successful   get_task_by_unix_pid()   call,   if	 the  process  is  the
       superuser.

RETURN VALUE
       This system call returns the previous value of the flag.

SEE ALSO
       get_task_by_unix_pid() (in the NEXTSTEP documentation available through
       Digital Librarian), exec(2), fork(2)
