-
- _b_u_f_f_e_r Specifies the starting address of the buffer (choice)
-
- _c_o_u_n_t Specifies the number of entries in the buffer (integer)
-
- _d_a_t_a_t_y_p_e Specifies the data type of the buffer (handle)

- _r_o_o_t Specifies the rank of the broadcast root (integer)
-
- _c_o_m_m Specifies the communicator (handle)
-
- _i_e_r_r_o_r Specifies the return code value for successful completion,
- which is in MPI_SUCCESS. MPI_SUCCESS is defined in the
