18.2.327. MPI_Ssend_init
MPI_Ssend_init - Builds a handle for a synchronous send.
18.2.327.1. SYNTAX
18.2.327.1.1. C Syntax
#include <mpi.h>
int MPI_Ssend_init(const void *buf, int count, MPI_Datatype datatype,
int dest, int tag, MPI_Comm comm, MPI_Request *request)
18.2.327.1.2. Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_SSEND_INIT(BUF, COUNT, DATATYPE, DEST, TAG, COMM, REQUEST,
IERROR)
<type> BUF(*)
INTEGER COUNT, DATATYPE, DEST, TAG, COMM, REQUEST, IERROR
18.2.327.1.3. Fortran 2008 Syntax

MPI_Ssend_init(buf, count, datatype, dest, tag, comm, request, ierror)
TYPE(*), DIMENSION(..), INTENT(IN), ASYNCHRONOUS :: buf

18.2.327.2. INPUT PARAMETERS
buf
: Initial address of send buffer (choice).count
: Number of elements to send (integer).datatype
: Type of each element (handle).dest
: Rank of destination (integer).tag
: Message tag (integer).comm
: Communicator (handle).
18.2.327.3. OUTPUT PARAMETERS
request
: Communication request (handle).IERROR
: Fortran only: Error status (integer).
18.2.327.4. DESCRIPTION
Creates a persistent communication object for a synchronous mode send operation, and binds to it all the arguments of a send operation.
A communication (send or receive) that uses a persistent request is initiated by the function MPI_Start.
18.2.327.5. 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.
