NAME

       MPI_File_write  -  Writes  a file starting at the location specified by
       the individual file pointer (blocking, noncollective).

SYNTAX

       C Syntax
           #include <mpi.h>
           int MPI_File_write(MPI_File fh, void *buf,
            int count, MPI_Datatype datatype,
            MPI_Status *status)

Fortran Syntax

           INCLUDE 'mpif.h'
           MPI_FILE_WRITE(FH,  BUF, COUNT,
                   DATATYPE, STATUS,  IERROR)
             <type> BUF(*)
             INTEGER FH, COUNT, DATATYPE, STATUS(MPI_STATUS_SIZE),
                 IERROR

C++ Syntax

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

       void MPI::File::Write(const void* buf, int count,
            const MPI::Datatype& datatype)

INPUT/OUTPUT PARAMETER

       fh        File handle (handle).

INPUT PARAMETERS

       buf       Initial address of buffer (choice).

       count     Number of elements in buffer (integer).

       datatype  Data type of each buffer element (handle).

OUTPUT PARAMETERS

       status    Status object (status).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_File_write attempts to write into the file associated with  fh  (at
       the  current individual file pointer position maintained by the system)
       a total number of count data items having datatype type from the user's
       buffer buf.  The data is written into those parts of the file specified
       by the current view.  MPI_File_write  stores  the  number  of  datatype
       elements  actually  written  in status.  All other fields of status are
       undefined.

       It is erroneous to call this function if MPI_MODE_SEQUENTIAL  mode  was
       specified when the file was opened.

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++
       functions  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.
