Required Routines for Data Type Definition

For each data type that you add, you must provide the following routines:

• compare

• dbtoev

• dhmax

• dhmin

• getempty

• hashprep

• helem

• hg_dtln

• hmax

• hmin

• keybuild

• length_check

• minmaxdv

• seglen

• tmcvt

• tmlen

• value_check

• xform

These routines are called using the following syntax:

status = fid_routine(scb, [arg1 [, arg2]], result)

The routines must return a 4-byte integer of type II_STATUS whose value represents the overall result of the function. A value of 0 (II_OK) means successful completion. A value of 5 (II_ERROR) means an error. In the case of an error, the query execution is terminated.
