Is there a way to use the C sprintf() function without it adding a ‘\0’ character at the end of its output? I need to write formatted text in the middle of a fixed width string.

There is no way to tell
sprintf()not to write a trailing null. What you can do is usesprintf()to write to a temporary string, and then something likestrncpy()to copy only the bytes that you want.
