NAME
MPI_Type_create_indexed_block - Creates an indexed data type with the same block length for all blocks. SYNTAX
C Syntax #include <mpi.h> int MPI_Type_create_indexed_block(int count, int blocklength, int array_of_displacements[], MPI_Datatype oldtype, MPI_Datatype *newtype) Fortran Syntax INCLUDE 'mpif.h' MPI_TYPE_CREATE_INDEXED_BLOCK(COUNT, BLOCKLENGTH, ARRAY_OF_DISPLACEMENTS, OLDTYPE, NEWTYPE, IERROR) INTEGER COUNT, BLOCKLENGTH, ARRAY_OF_DISPLACEMENTS(*), OLDTYPE, NEWTYPE, IERROR C++ Syntax #include <mpi.h> MPI::Datatype MPI::Datatype::Create_indexed_block( int count, int blocklength, const int array_of_displacements[]) const INPUT PARAMETERS
count Length of array of displacements (integer). blocklength Size of block (integer). array_of_displacements Array of displacements (array of integers). oldtype Old data type (handle). OUTPUT PARAMETERS
newtype New data type (handle). IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_Type_create_indexed_block creates an indexed data type with the same block length for all blocks. 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. SEE ALSO

NAME
MPI_Type_create_struct - Creates a structured data type. SYNTAX
C Syntax #include <mpi.h> int MPI_Type_create_struct(int count, int array_of_blocklengths[], MPI_Aint array_of_displacements[], MPI_Datatype array_of_types[], MPI_Datatype *newtype) Fortran Syntax (see FORTRAN 77 NOTES) INCLUDE 'mpif.h' MPI_TYPE_CREATE_STRUCT(COUNT, ARRAY_OF_BLOCKLENGTHS, ARRAY_OF_DISPLACEMENTS, ARRAY_OF_TYPES, NEWTYPE, IERROR) INTEGER COUNT, ARRAY_OF_BLOCKLENGTHS(*), ARRAY_OF_TYPES(*), INTEGER NEWTYPE, IERROR INTEGER(KIND=MPI_ADDRESS_KIND) ARRAY_OF_DISPLACEMENTS(*) C++ Syntax #include <mpi.h> static MPI::Datatype MPI::Datatype::Create_struct(int count, const int array_of_blocklengths[], const MPI::Aint array_of_displacements[], const MPI::Datatype array_of_types[]) INPUT PARAMETERS
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). OUTPUT PARAMETERS
newtype New data type (handle). IERROR Fortran only: Error status (integer). DESCRIPTION
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. FORTRAN 77 NOTES 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. 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.
