DESCRIPTION
     _G_e_t_e_n_v searches the environment list (see _e_n_v_i_r_o_n(7)) for  a
     string  of  the  form _n_a_m_e=_v_a_l_u_e and returns _v_a_l_u_e if such a
     string is present, otherwise 0 (NULL).  _N_a_m_e may  be  either
     the   desired   name,   null-terminated,   or  of  the  form
     _n_a_m_e=_v_a_l_u_e, in which case _g_e_t_e_n_v uses  the  portion  to  the
     left of the "=" as the search key.
