Dan, it wasn't necessary to lapse into sarcasm. Why not just follow the
example of the prior respondents and answer the question in a serious
and congenial manner (or refrain from making any reply if the question
has already been answered)? Expertise does not excuse bad manners.
This could be a sign I've been hanging around c.l.c. too long, but
Dan's answer is perfectly appropriate (if a bit brusque, but that's
part of Dan's charm). Answers to basic questions such as this are
best found in your handy C reference manual, not in an online
newsgroup where there is some delay in getting an answer, and where at
least one of the answers you get will be wrong or useless.
The OP needs to get into the habit of checking his C reference manual
*first*; if he has additional questions, he needs to check out the
FAQ; and then, if he still needs guidance, ask a question here.
