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 methods 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.

       Before the error value is returned, the current MPI error handler is called. For MPI I/O function errors, the default error handler is  set
       to  MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may
       be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
