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.
