17.2.109. MPI_File_get_position

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

17.2.109.1. SYNTAX

17.2.109.1.1. C Syntax

#include <mpi.h>

int MPI_File_get_position(MPI_File fh, MPI_Offset *offset)

17.2.109.1.2. Fortran Syntax (see FORTRAN 77 NOTES)

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

17.2.109.1.3. Fortran 2008 Syntax

USE mpi_f08
MPI_File_get_position(fh, offset, ierror)
     TYPE(MPI_File), INTENT(IN) :: fh
     INTEGER(KIND=MPI_OFFSET_KIND), INTENT(OUT) :: offset
     INTEGER, OPTIONAL, INTENT(OUT) :: ierror

17.2.109.2. INPUT PARAMETER

fh: File handle (handle).

17.2.109.3. OUTPUT PARAMETERS

offset: Offset of the individual file pointer (integer).
IERROR: Fortran only: Error status (integer).

17.2.109.4. 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.

17.2.109.5. 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.

17.2.109.6. ERRORS

Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.

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.
