"A static cast like that should never be required for an assignment in a C++ program."

Wouldn't it be just as easy to say, "Hey Jeff, you'd be better advised to use get_string().". Disgegarding the comment in coldata.h which says.. 'If you know your data is a null-terminated C string, just cast this object to const char *...' " :o) Of course I realize this is all the result of a multi person, collaborative effort.

Hey, as it turns out... my unix admin, ignored my requests and installed 2.2.3 instead of 2.3.2 (guess this whole universal practice of symbollic linking to the correct .so sorts of undermines the versioning of filenames, huh)... so my 2.3.2 code was hitting the 2.2.3 library. Once the correct .so was put out there... surprise, surprise... everything works.

Anyway, I'm sure the Don Rickle's style responses here no doubt have their own appeal to the rest of the audience who actually know what they're doing.   As for me... I'll quietly sink back into the shadows now. :o)
