MPI_File_write_shared

MPI_File_write_shared - Writes a file using the shared file pointer (blocking, noncollective).

SYNTAX

C Syntax

#include <mpi.h>

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

Fortran Syntax

USE MPI
! or the older form: INCLUDE 'mpif.h'

MPI_FILE_WRITE_SHARED(FH, BUF, COUNT, DATATYPE, STATUS, IERROR)
    <type>  BUF(*)
      INTEGER   FH, COUNT, DATATYPE, STATUS(MPI_STATUS_SIZE), IERROR

Fortran 2008 Syntax

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

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.
