hmin Routine—Create Histogram Value for Minimum Value
This routine is used by the optimizer to obtain the histogram value for the smallest value of a type. For a discussion of histograms, see helem Routine.
Note: The smallest value for the given data type is expected to be known implicitly by the routine.
Place the address of this routine in the dtd_hmim_addr field of the IIADD_DT_DFN structure. If the II_DT_NOHISTOGRAM attribute is present, then this routine is not necessary.
