NAME

       MPI_File_get_position - Returns the current position of the individual file pointer.

SYNTAX

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

Fortran Syntax (see FORTRAN 77 NOTES)

           INCLUDE 'mpif.h'
           MPI_FILE_GET_POSITION(FH, OFFSET, IERROR)
                  INTEGER FH, IERROR
                  INTEGER(KIND=MPI_OFFSET_KIND) OFFSET

C++ Syntax

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

INPUT PARAMETER

       fh        File handle (handle).

OUTPUT PARAMETERS

       offset    Offset of the individual file pointer (integer).

       IERROR    Fortran only: Error status (integer).

DESCRIPTION

       MPI_File_get_position  returns,  in  offset,  the  current position of the individual 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.
