Strings in C - help

RE: Strings in C - help
Thanks, but it looks like ever since I found a workaround for the issues I was having with strcat(), I have understood how to extract the bytes I want from an area set aside for a chr string.

In my case, after I put 64 bytes in a 67 byte location reserved for tmp I only use a function that specifically extracts 64 bytes and does not look for a nul.

It appears that my understanding, which was enough to make my code work, crossed some sort of convention (or defined semantics) such that I must be careful that I do not use a str function that looks for a nul when it is maybe an issue like that which I am trying to solve in the strcat() issue.

I don't think that having to remember this is any harder that having to remember, all the time (regardless of whether I have crossed a convention), not to assign to a char reserved location, more bytes than it has reserved.

I have to say, and this is a personal assessment only so lets not try to defend our views ad infinitum, that my experience with this C 'environment' makes me feel like I have gone back to the stone age based on my 30+ years of programming in basic and object oriented VB6.

And thanks John for drilling this string null issue so many times here as I am sure it will benefit anyone having string issues.
