-
-
-
- _s_e_n_d_b_u_f Specifies the starting address of the send buffer (choice)
-
- _c_o_u_n_t Specifies the number of elements in the input buffer (integer)
-
- _d_a_t_a_t_y_p_e Specifies the data type of elements of the input buffer
- (handle)
-
- _o_p Specifies the operation (handle)
-
- _c_o_m_m Specifies the communicator (handle)
-
- _r_e_c_v_b_u_f Returns the starting address of the receive buffer (choice)
-
- _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 mmmmppppiiiiffff....hhhh
- file.
