--- Creates an indexed datatype

Input Parameters

count: number of blocks -- also number of entries in array_of_displacements and array_of_blocklengths (nonnegative integer)

array_of_displacements: displacement for each block, in multiples of oldtype extent (array of integer)

oldtype: old datatype (handle)

Output Parameter

newtype: new datatype (handle)
