Strncpy() and strncat()

• Still requires extra attention

  • strncpy() leaves dest unterminated if
  • sizeof(dest) <= len(src)
  • Usually followed by forcing a null char in the last character byte.
  • char dest[MAXLEN];

• strncpy(dest,src,MAXLEN);

• dest[MAXLEN - 1] = '\0';

• Slower

  • strncpy() zero-fills remainder of dest
  • Typical usage: large dest, small src
