NAME

       MPI_File_get_position_shared - Returns the current position of the shared file pointer.

SYNTAX

C Syntax

           #include <mpi.h>
           int MPI_File_get_position_shared(MPI_File fh, MPI_Offset *offset)

Fortran Syntax (see FORTRAN 77 NOTES)

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_FILE_GET_POSITION_SHARED(FH, OFFSET, IERROR)
            INTEGER   FH, IERROR
            INTEGER(KIND=MPI_OFFSET_KIND) OFFSET

C++ Syntax

       #include <mpi.h>
       MPI::Offset MPI::File::Get_position_shared() const

INPUT PARAMETER

       fh        File handle (handle).

OUTPUT PARAMETERS

       offset    Offset of the shared file pointer (integer).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_File_get_position_shared returns, in offset, the current position of the shared file pointer in etype
       units relative to the current displacement and file type.

FORTRAN 77 NOTES

       The MPI standard prescribes portable Fortran syntax for the OFFSET argument  only  for  Fortran  90.  Sun
       FORTRAN 77 users may use the non-portable syntax

            INTEGER*MPI_OFFSET_KIND OFFSET

       where  MPI_ADDRESS_KIND  is  a constant defined in mpif.h and gives the length of the declared integer in
       bytes.

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.
