        ^^^^^^^^^^ This buffer is probably too short for what you're
trying to do. At the very least, you should limit the maximal output
width of your sprintf() format accordingly.

You don't show what function "char" is. 

And I'm quite sure you don't want the code number of the character you
input, as a decimal string, which is what this sprintf() call will give 
you. What you want would be much easier to do like this:

	buffer[0] = x;
	buffer[1] = '\0';

This makes the string in "buffer" read "1", if you typed '1'.
