MPI_Type_size(3OpenMPI)                                                              MPI_Type_size(3OpenMPI)



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.
