     The _i_p_c_r_m command will remove one or more specified sema-
     phore or shared memory identifiers. The identifiers are
     specified by the following _o_p_t_i_o_n_s:

     ----mmmm _s_h_m_i_d  removes the shared memory identifier _s_h_m_i_d from
               the system. The shared memory segment and data
               structure associated with it are destroyed after
               the last detach.

     ----ssss _s_e_m_i_d  removes the semaphore identifier _s_e_m_i_d from the
               system and destroys the set of semaphores and data
               structure associated with it.

     ----MMMM _s_h_m_k_e_y removes the shared memory identifier, created with
               key _s_h_m_k_e_y, from the system. The shared memory
               segment and data structure associated with it are
               destroyed after the last detach.

     ----SSSS _s_e_m_k_e_y removes the semaphore identifier, created with key
               _s_e_m_k_e_y, from the system and destroys the set of
               semaphores and data structure associated with it.

     The details of the removes are described in _s_h_m_c_t_l(2), and
     _s_e_m_c_t_l(2).  The identifiers and keys may be found by using
     _i_p_c_s(1).
