Fill methods level API
There are fill methods:

All fill methods consist of two functions: initialization and data generation. The first function saves fill methods properties into internal structures and prepares handle (DG_HANDLE type). The second (data generation) function accepts this handle as parameter.

Important: before use you should copy to local buffer result of any function of this API level.

All functions of this group return generated value as string. The user should made required conversions manually.

SDK offers function PrevValue that returns previously generated value for specified method's handle. This function is helpful for depended values generation.
char *PrevValue(DG_HANDLE handle)
string PrevValue(int handle)
