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 nonportable 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.
