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.
