17.2.329. MPI_Ssend
MPI_Ssend - Standard synchronous send.
17.2.329.1. SYNTAX
17.2.329.1.1. C Syntax
#include <mpi.h>
int MPI_Ssend(const void *buf, int count, MPI_Datatype datatype, int dest,
int tag, MPI_Comm comm)
17.2.329.1.2. Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_SSEND(BUF, COUNT, DATATYPE, DEST, TAG, COMM, IERROR)
<type> BUF(*)
INTEGER COUNT, DATATYPE, DEST, TAG, COMM, IERROR
17.2.329.1.3. Fortran 2008 Syntax
USE mpi_f08
MPI_Ssend(buf, count, datatype, dest, tag, comm, ierror)
TYPE(*), DIMENSION(..), INTENT(IN) :: buf
INTEGER, INTENT(IN) :: count, dest, tag
TYPE(MPI_Datatype), INTENT(IN) :: datatype
TYPE(MPI_Comm), INTENT(IN) :: comm
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
17.2.329.2. 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).
17.2.329.3. OUTPUT PARAMETER
IERROR
: Fortran only: Error status (integer).
17.2.329.4. DESCRIPTION
MPI_Ssend performs a synchronous-mode, blocking send. See the MPI-1 Standard for more detailed information about such sends.
17.2.329.5. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
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.
