MPI_File_get_position_shared(3)    Open MPI    MPI_File_get_position_shared(3)



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.
