Thread: sscanf causing problems

Hello,
I am trying to use sscanf in a program. It compiles fine, but it is causing the run to hang up everytime.
This is the code that does it. If I comment it out, the program runs fine without it, just doesn't function, of course.

Code:

sscanf((chrString),"%c%c%c", 
          &gObj->vertices[count].xCoord,	
         &gObj->vertices[count].yCoord,
         &gObj->vertices[count].zCoord);

Any Idea why this would be?
