sprintf

#include <stdio.h> /* including standard library */
//#include <windows.h> /* uncomment this for Windows */
 
    int sprintf(char *str, const char *format, ...);

Like fprintf, but output written into string s, which must be large enough to hold the output, rather than to a stream. Output is NUL-terminated. Returns length (excluding the terminating NUL).
