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 dis-
placement 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-por-
table 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++ func-
tions 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
