I applause you for asking a question on C level, also I applause you for asking same question on p5p list.

Some people here afraid of postng to p5p, I do not know why. it's a shame you have some knowledge and share it on PM but refuse sharing this on p5p. But this happens, and, unfortunately, quite not rare case btw,,,

Sorry for not giving you good answer for question, may be I'll do it tomorrow
(feel free to '--' me for just applausing and not giving answers... what do you expect rfom stupid dog?)
