       Some of the functionality described on this reference page extends the
       ISO C standard. Applications shall define the appropriate feature test
       macro (see the System Interfaces volume of POSIX.1-2008, _S_e_c_t_i_o_n _2_._2,
       _T_h_e _C_o_m_p_i_l_a_t_i_o_n _E_n_v_i_r_o_n_m_e_n_t) to enable the visibility of these symbols
       in this header.

       The _<_s_e_t_j_m_p_._h_> header shall define the array types jjmmpp__bbuuff and
       ssiiggjjmmpp__bbuuff.

       The following shall be declared as functions and may also be defined as
       macros. Function prototypes shall be provided.

           vvooiidd   __lloonnggjjmmpp((jjmmpp__bbuuff,, iinntt));;
           vvooiidd   lloonnggjjmmpp((jjmmpp__bbuuff,, iinntt));;
           vvooiidd   ssiigglloonnggjjmmpp((ssiiggjjmmpp__bbuuff,, iinntt));;

       The following may be declared as functions, or defined as macros, or
       both. If functions are declared, function prototypes shall be provided.

           iinntt    __sseettjjmmpp((jjmmpp__bbuuff));;
           iinntt    sseettjjmmpp((jjmmpp__bbuuff));;
