Alternatives to strtok?

Ok, I am storing strings that contain '\n' in a char *. I need to print the strings one by one (delimted by the newline). I was using strtok but it clobbers my original copy of the data, replacing every newline with a null terminator. Any recommendations on how I 'untokenize' my original string? Would it be better to create a copy of the string? or is there a good alternative to strtok / strtok_r?

Thanks in advance,

Why not add the newline when you print the data?

printf("%s\n", token);

Wait now I see what your saying, yeah making a copy would probably be easiest since your gonna lose your delimiters also. I can't think of any alternatives that would be any more efficient and strtok is the most efficient way to parse delimitted strings.

Alright, thanks. I'm displaying the string in Xlib (XDrawString... is there another way) and it doesn't print newlines... it just dumps everything onto one line. So I have to go through the carriage returns and print each one by one.

Thanks for the help,

Well there's strsep() but it has the same problem

I've just copied the string when I need to not clobber it.

Thanks for the tips. I've gone with the copying and it is working out well.
