- The MMMMPPPPIIII____SSSSeeeennnndddd routine performs a basic send operation. This routine
- accepts the following parameters:
-
- _b_u_f Specifies the initial address of the send buffer (choice)
-
- _c_o_u_n_t Specifies the number of elements in the send buffer
- (nonnegative integer)

-
-
-
- _d_a_t_a_t_y_p_e Specifies the data type of each send buffer element (handle)
-
- _d_e_s_t Specifies the rank of the destination (integer)
-
- _t_a_g Specifies the message tag (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 mmmmppppiiiiffff....hhhh
- file.
-
- NNNNOOOOTTTTEEEESSSS
- This routine may block until the message is received.
-
- All MPI routines in Fortran (except for MMMMPPPPIIII____WWWWttttiiiimmmmeeee(3) and MMMMPPPPIIII____WWWWttttiiiicccckkkk(3) )
- have an additional _i_e_r_r argument at the end of the argument list. _i_e_r_r
- is an integer and has the same meaning as the return value of the routine
- in C. In Fortran, MPI routines are subroutines and are invoked with the
- CCCCAAAALLLLLLLL statement. Additionally, in Fortran, all MPI objects (for example,
- MMMMPPPPIIII____DDDDaaaattttaaaattttyyyyppppeeee and MMMMPPPPIIII____CCCCoooommmmmmmm) are of type integer.
