Note that passing structures by value, rather than by reference (either through pointers or C++ references) means that the entire struct is being pushed onto and popped off of the stack. This can be very expensive, and potentially damaging, if all of a structure's members (such as pointers to data, etc.) aren't self-contained; you can get situations where you have two structure's with inconsistent states using overlapping memory that are not taking into account the other. -- Erik Max Francis / email max AT alcyone DOT com / whois mf303 / icq 16063900 Alcyone Systems / irc maxxon (efnet) / finger max AT sade DOT alcyone DOT com San Jose, CA / languages En, Eo / web http://www.alcyone.com/max/ USA / icbm 37 20 07 N 121 53 38 W / &tSftDotIotE \ / Many things are lost for want of asking. / (an English proverb)
