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 multi- plicity. 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. 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. Open MPI 1.2 September 2006 MPI_Type_size(3OpenMPI)

NAME
MPI_Type_get_extent - Returns the lower bound and extent of a data type. SYNTAX
C Syntax #include <mpi.h> int MPI_Type_get_extent(MPI_Datatype datatype, MPI_Aint *lb, MPI_Aint *extent) Fortran Syntax (see FORTRAN 77 NOTES) INCLUDE 'mpif.h' MPI_TYPE_GET_EXTENT(DATATYPE, LB, EXTENT, IERROR) INTEGER DATATYPE, IERROR INTEGER(KIND=MPI_ADDRESS_KIND) LB, EXTENT C++ Syntax #include <mpi.h> void MPI::Datatype::Get_extent(MPI::Aint& lb, MPI::Aint& extent) const INPUT PARAMETER
datatype Data type (handle). OUTPUT PARAMETERS
lb Lower bound of data type (integer). extent Data type extent (integer). IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_Type_get_extent returns the lower bound and the extent of datatype. NOTE
Use of MPI_Type_get_extent is strongly recommended over the old MPI-1 functions MPI_Type_extent and MPI_Type_lb. FORTRAN 77 NOTES The MPI standard prescribes portable Fortran syntax for the LB and EXTENT arguments only for Fortran 90. FORTRAN 77 users may use the non- portable syntax INTEGER*MPI_ADDRESS_KIND LB or INTEGER*MPI_ADDRESS_KIND EXTENT where MPI_ADDRESS_KIND is a constant defined in mpif.h and gives the length of the declared integer in bytes.
