MPI_Type_size(3)                   Open MPI                   MPI_Type_size(3)



NAME
       MPI_Type_size - Returns the number of bytes occupied by entries in a
       data type.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Type_size(MPI_Datatype datatype, int *size)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_TYPE_SIZE(DATATYPE, SIZE, IERROR)
            INTEGER   DATATYPE, SIZE, IERROR


C++ Syntax
       #include <mpi.h>
       int Datatype::Get_size() const


INPUT PARAMETER
       datatype  Datatype (handle).



OUTPUT PARAMETERS
       size      Datatype size (integer).


       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_Type_size returns the total size, in bytes, of the entries in the
       type signature associated with datatype; i.e., the total size of the
       data in a message that would be created with this datatype. Entries
       that occur multiple times in the datatype are counted with their
       multiplicity.


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. 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.
