MPI_File_write -  Write using individual file pointer


SYNOPSIS

       C:

            #include "mpi.h"

            int MPI_File_write(MPI_File fh, void *buf, int count,
            MPI_Datatype datatype, MPI_Status *status)

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            <type> BUF(*)
            INTEGER fh, count, datatype, status(MPI_STATUS_SIZE),
            ierror

            CALL MPI_FILE_WRITE(fh, buf, count, datatype,
            status, ierror)


DESCRIPTION

       MPI_File_write writes a file using the individual file
       pointer.

       MPI_File_write accepts the following arguments:

       fh        Specifies the file handle (handle)

       buf       Specifies the initial address of the buffer
                 (choice)

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

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

       status    Returns the status object (status)

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

   Notes for Fortran
       All MPI objects (for example, MPI_Datatype, MPI_Comm,
       MPI_File) are of type INTEGER.
