No, it would not. strncpy does NOT append the trailing 0 if the length of the source is greater than or equal to the count.

Using sizeof(dst)-1 will leave the last byte in the buffer unchanged. If dst is on the stack there is no guarantee the string is terminated. To be sure, you would *also* need to add dst[sizeof(dst)-1] = 0;

C'mon people, this really is beginner stuff. Please RTFM before you post well-meaning advice.

You might also like to look at the bsd-style strlcpy/strlcat functions. Received on Fri Nov 22 01:45:47 2002
