NAME
MPI_File_create_errhandler - Creates an MPI-style error handler that can be attached to a file. SYNTAX
C Syntax #include <mpi.h> int MPI_File_create_errhandler(MPI_File_errhandler_fn *function, MPI_Errhandler *errhandler) Fortran Syntax INCLUDE 'mpif.h' MPI_FILE_CREATE_ERRHANDLER(FUNCTION, ERRHANDLER, IERROR) EXTERNAL FUNCTION INTEGER ERRHANDLER, IERROR C++ Syntax #include <mpi.h> static MPI::Errhandler MPI::File::Create_errhandler(MPI::File::Errhandler_fn* function) INPUT PARAMETER
function User-defined error handling procedure (function). OUTPUT PARAMETERS
errhandler MPI error handler (handle). IERROR Fortran only: Error status (integer). DESCRIPTION
Registers the user routine function for use as an MPI exception handler. Returns in errhandler a handle to the registered exception han- dler. In the C language, the user routine function should be a C function of type MPI_File_errhandler_fn, which is defined as typedef void (MPI_File_errhandler_fn)(MPI_File *, int *, ...); The first argument to function is the file in use. The second is the error code to be returned by the MPI routine that raised the error. In the Fortran language, the user routine should be of the form: SUBROUTINE FILE_ERRHANDLER_FN(FILE, ERROR_CODE, ...) INTEGER FILE, ERROR_CODE In C++, the user routine function should be of the form: typedef void MPI::File::Errhandler_fn(MPI::File &, int *, ...); 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 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. Open MPI 1.2 September 2006 MPI_File_create_errhandler(3OpenMPI)

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 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.
