MPIR_Type_indexed

Synopsis

int MPIR_Type_indexed(int count,
                      const int *blocklength_array,
                      const void *displacement_array,
                      int dispinbytes, MPI_Datatype oldtype, MPI_Datatype * newtype)

Input Parameters

count

number of blocks in type

blocklength_array

number of elements in each block

displacement_array

offsets of blocks from start of type (see next parameter for units)

dispinbytes

if nonzero, then displacements are in bytes (the displacement_array is an array of ints), otherwise they in terms of extent of oldtype (the displacement_array is an array of MPI_Aints)

oldtype

type (using handle) of datatype on which new type is based

Output Parameters

newtype

handle of new indexed datatype

Return Value
