- The __d_a_e_m_o_n_i_z_e function does the common work needed ``to put a function
- into the background,'' or to make it into a ``daemon.'' That generally
- includes forking a new process, closing most files, and releasing the
- controlling tty.
-
- If ffffllllaaaaggggssss &&&& ____DDDDFFFF____NNNNOOOOFFFFOOOORRRRKKKK is 0, then a new process in a new session is
- started. Debugging is often easier with ffffllllaaaaggggssss set to contain ____DDDDFFFF____NNNNOOOOFFFFOOOORRRRKKKK.
-
- If ffffllllaaaaggggssss &&&& ____DDDDFFFF____NNNNOOOOCCCCHHHHDDDDIIIIRRRR is 0, then the current working directory is
- changed to /. Otherwise, the current working directory is unchanged.
-
- If ffffllllaaaaggggssss &&&& ____DDDDFFFF____NNNNOOOOCCCCLLLLOOOOSSSSEEEE is 0, then all file descriptors except ffffdddd1111, ffffdddd2222,
- and ffffdddd3333 are closed. Because __d_a_e_m_o_n_i_z_e closes all file descriptors,
- _c_l_o_s_e_l_o_g() is called to stop logging cleanly. The ffffdddd# arguments should
- be -1 if they are not file descriptors to be left open.

- The returned value -1 indicates that one of the necessary system calls
- failed.
