       The _g_a_i___s_t_r_e_r_r_o_r() function shall return a text string describing an
       error value for the _g_e_t_a_d_d_r_i_n_f_o() and _g_e_t_n_a_m_e_i_n_f_o() functions listed in
       the _<_n_e_t_d_b_._h_> header.

       When the _e_c_o_d_e argument is one of the following values listed in the
       _<_n_e_t_d_b_._h_> header:

       [[EEAAII__AAGGAAIINN]]      [[EEAAII__NNOONNAAMMEE]]
       [[EEAAII__BBAADDFFLLAAGGSS]]   [[EEAAII__OOVVEERRFFLLOOWW]]

       [[EEAAII__MMEEMMOORRYY]]     [[EEAAII__SSYYSSTTEEMM]]

       the function return value shall point to a string describing the error.
       If the argument is not one of those values, the function shall return a
       pointer to a string whose contents indicate an unknown error.

RREETTUURRNN VVAALLUUEE
       Upon successful completion, _g_a_i___s_t_r_e_r_r_o_r() shall return a pointer to an
       implementation-defined string.
