MPI_File_get_position_shared(3OpenMPI)                                MPI_File_get_position_shared(3OpenMPI)



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)
           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.
