For string functions, start with "man string". If you do not already have a copy, obtain a copy of _The C Programming Language_, 2nd edition, by K&R. You must do this if you program in C.

It'sabout two lines long :-) Okay. I was just wondering if it was predefined. Thanks! Erik ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

You're both wrong. :-) You are talking about Perl's unshift routine. -- Bob Bell <[EMAIL PROTECTED]> - "Software gets slower faster than hardware gets faster!" -- "Wirth's Law" - Niklaus Wirth, famous computer scientist ___ gnhlug-discuss mailing list [EMAIL PROTECTED] http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

Also check out _C -- A Reference Manual_ by Harbison and Steele. If you're interested in C++, you might check out the STL -- problems like what you're alluding to can be easily solved with this library. But if you're supposed to use C and the C standard library, then this option is not available to you. Regards, --kevin -- Kevin D. Clark / Cetacean Networks / Portsmouth, N.H.

I would like to eventually learn C++. But first I need to get a bit more comfortable in C. (One thing this C class has taught me is a real appreciation for Java. :) I'll have to remember STL for later, though.
