I want to read the part between quotation marks of the fowllowing line into destination: shader "models/monsters/zombie/fatty/fatty" I used this: sscanf(currLine, "%*s \"%s\"", destination); but when sscanf returns, destination has one more char than I expected: the last quotation mark. but in the format string, I've already explicitly written the last quotation mark as \", why would it still count it belonging to the %s part?

Check the definition of sscanf. It's not as smart as you think. Specifically:
scanf types:
s: String of characters. This will read subsequent characters until a whitespace is found (whitespace characters are blank, newline and tab)..

You might want to invest in one of these.

That's not all there is to scanf. Without reaching for a regex library:

#include <stdio.h>int main(){  char destination[256];  // with spaces in the middle, just to show it works.  const char* currLine = "shader \"models/monst  ers/  zombie/fa  tty/f atty\"";  int n = sscanf( currLine, "%*s \"%[^\"]\"", destination);  printf("%d   %s", n, destination);}

It shows how dumb the forums strings parser is [grin] j/k [attention] appreciation!
