NAME

       MPI_File_iwrite_shared  -  Writes  a file using the shared file pointer
       (nonblocking, noncollective).

SYNTAX

       C Syntax
           #include <mpi.h>
           int MPI_File_(MPI_File fh, void *buf, int count, MPI_Datatype
                  datatype, MPI_Request *request)

       Fortran Syntax
           INCLUDE 'mpif.h'
           MPI_File_(FH, BUF, COUNT, DATATYPE, REQUEST, IERROR)
                 <type>         BUF(*)
                 INTEGER        FH, COUNT, DATATYPE, REQUEST, IERROR

C++ Syntax

       #include <mpi.h>
       MPI::Request MPI::File::Iwrite_shared(const void* buf, int count,
            const MPI::Datatype& datatype)

INPUT/OUTPUT PARAMETER

       fh        File handle (handle).

INPUT PARAMETERS

       count     Number of elements in buffer (integer).

       datatype  Data type of each buffer element (handle).

OUTPUT PARAMETERS

       buf       Initial address of buffer (choice).

       request   Request object (handle).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_File_iwrite_shared is a nonblocking routine that  uses  the  shared
       file  pointer  to write files. The order of serialization is not deter-
       ministic for this noncollective routine, so you need to use other meth-
       ods of synchronization to impose a particular order.

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++  func-
       tions  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.
