- count
- Number of blocks (integer) -- also number of entries
in arrays array_of_types, array_of_displacements, and array_of_blocklengths.
- array_of_blocklengths
- Number of elements in each block (array of integers).
- array_of_displacements
- Byte displacement of each block (array of integers).
- array_of_types
- Type of elements in each block (array of handles to data-type
objects).
- newtype
- New data type (handle).
- IERROR
- Fortran
only: Error status (integer).
MPI_Type_create_struct creates
a structured data type. This routine replaces MPI_Type_struct, which is
now deprecated.
NOTE - This routine replaces MPI_Type_struct, which is deprecated.
See the man page MPI_Type_struct(3) for information about that routine.
The MPI standard prescribes portable Fortran syntax for
the ARRAY_OF_DISPLACEMENTS(*) argument only for Fortran 90. FORTRAN 77
users may use the non-portable syntax
INTEGER*MPI_ADDRESS_KIND ARRAY_OF_DISPLACEMENTS(*)
where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length
of the declared integer in bytes.
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.
By default, this error handler aborts the MPI job, except for I/O function
errors. The error handler may be changed with MPI_Comm_set_errhandler; the
predefined error handler MPI_ERRORS_RETURN may be used to cause error values
to be returned. Note that MPI does not guarantee that an MPI program can
continue past an error.
