Linux does not agree:

strxfrm ((null), hello, 0) = 5
strxfrm (buf, hello, 9) = 5
strxfrm (buf, hello, 3) = 5

"returns the length of the transformed string" means the
transformation of the source, not the stored results.  I.e., the
length *before* truncating to fit the buffer.

Remember, "n" is the size of the output buffer, not the size of the
input string.
