This will wrong when strlen(fname) is 30. strncat() will copy only 30
bytes, without terminal NUL.
That's not how strncat() works. strncat(dest, src, n) writes n+1 chars
to the end of dest: n chars from src and +1 for the final NUL char. For
this reason dest must be large enough to hold strlen(dest) + n + 1 chars.
Oh, true. strncat() always results NUL-terminated string. It's strncpy()
can produce not NUL-terminated string. Sorry for noise.
