Docs for ESQL/C low levels?

Greetings, I have looked at the code generated by the ESQL/C preprocessor and seen calls like the following: _iqdatabase _iqdscribe _iqprepare What are the chances of getting documentation for these "low level" calls? How often do the calls change from one release to the next? (i.e. number and order of parameters) Is it taboo to even mentions these things? ;-) As always, thanks for any help. --- Chris Hardin chris@green.att.com ...!att!green!chris 404.750.5246
