MPI_Issend(3)

NAME
     MPI_Issend - Starts a nonblocking synchronous send

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Issend( buf, count, datatype, dest, tag,
          comm, request )
          void             *buf;
          int              count;
          MPI_Datatype     datatype;
          int              dest;
          int              tag;
          MPI_Comm         comm;
          MPI_Request      *request;


     C++:

          #include <mpi.h>

          Request Comm::Issend(
          const void*       buf,
          int               count,
          const Datatype&   datatype,
          int               dest,
          int               tag) const


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          <type> BUF(*)
          INTEGER count, datatype, dest, tag, comm, request, ierror

          CALL MPI_ISSEND( buf, count, datatype, dest, tag, comm, request, ierror)


STANDARDS
     This release implements the MPI 1.2 standard, as documented by the MPI
     Forum in the spring 1997 release of MPI:  A Message Passing Interface
     Standard.

DESCRIPTION
     The MPI_Issend routine starts a nonblocking synchronous send operation.
     This routine accepts the following parameters:
     buf       Specifies the initial address of the send buffer (choice)

     count     Specifies the number of elements in the send buffer (integer)

     datatype  Specifies the data type of each send buffer element (handle)

     dest      Specifies the rank of the destination (integer)

     tag       Specifies the message tag (integer)

     comm      Specifies the communicator (handle)

     request   Returns the communication request (handle)

     ierror    Specifies the return code value for successful completion,
               which is in MPI_SUCCESS.  MPI_SUCCESS is defined in the mpif.h
               file.
