MPI_Ssend(3OpenMPI)                                                                      MPI_Ssend(3OpenMPI)



NAME
       MPI_Ssend - Standard synchronous send.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Ssend(void *buf, int count, MPI_Datatype datatype, int dest,
            int tag, MPI_Comm comm)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_SSEND(BUF, COUNT, DATATYPE, DEST, TAG, COMM, IERROR)
            <type>    BUF(*)
            INTEGER   COUNT, DATATYPE, DEST, TAG, COMM, IERROR


C++ Syntax
       #include <mpi.h>
       void Comm::Ssend(const void* buf, int count, const Datatype&
            datatype, int dest, int tag) const


INPUT PARAMETERS
       buf       Initial address of send buffer (choice).

       count     Number of elements in send buffer (nonnegative integer).

       datatype  Datatype of each send buffer element (handle).

       dest      Rank of destination (integer).

       tag       Message tag (integer).

       comm      Communicator (handle).


OUTPUT PARAMETER
       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Ssend performs a synchronous-mode, blocking send. See the MPI-1 Standard for more detailed infor-mation information
       mation about such sends.


ERRORS
       Almost all MPI routines return an error value; C routines as the value of the  function  and  Fortran
       routines  in  the  last argument. C++ functions do not return errors. If the default error handler is
       set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to  throw
       an MPI:Exception object.

       Before  the  error value is returned, the current MPI error handler is called. By default, this error
       handler aborts the MPI job, except for I/O function errors. The error handler  may  be  changed  with
       MPI_Comm_set_errhandler;  the  predefined  error handler MPI_ERRORS_RETURN may be used to cause error
       values to be returned. Note that MPI does not guarantee that an MPI  program  can  continue  past  an
       error.
