.. _mpi_file_write_shared: MPI_File_write_shared ===================== .. include_body :ref:`MPI_File_write_shared` |mdash| Writes a file using the shared file pointer (blocking, noncollective). SYNTAX ------ C Syntax ^^^^^^^^ .. code-block:: c #include int MPI_File_write_shared(MPI_File fh, const void *buf, int count, MPI_Datatype datatype, MPI_Status *status) Fortran Syntax ^^^^^^^^^^^^^^ .. code-block:: fortran USE MPI ! or the older form: INCLUDE 'mpif.h' MPI_FILE_WRITE_SHARED(FH, BUF, COUNT, DATATYPE, STATUS, IERROR) BUF(*) INTEGER FH, COUNT, DATATYPE, STATUS(MPI_STATUS_SIZE), IERROR Fortran 2008 Syntax ^^^^^^^^^^^^^^^^^^^ .. code-block:: fortran USE mpi_f08 MPI_File_write_shared(fh, buf, count, datatype, status, ierror) TYPE(MPI_File), INTENT(IN) :: fh TYPE(*), DIMENSION(..), INTENT(IN) :: buf INTEGER, INTENT(IN) :: count TYPE(MPI_Datatype), INTENT(IN) :: datatype TYPE(MPI_Status) :: status INTEGER, OPTIONAL, INTENT(OUT) :: ierror 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 ----------- :ref:`MPI_File_write_shared` is a blocking routine that uses the shared file pointer to write files. The order of serialization is not deterministic for this noncollective routine. ERRORS ------ .. include:: ./ERRORS.rst
