My draft copy of C99 sez:

    The snprintf function returns the number of characters that would have
    been written had n been sufficiently large, not counting the
    terminating null character, or a negative value if an encoding error

-1 isn't mentioned at all.  What does the final C99 say?  Regardless, MS's
pre-C99 implementation says:

    _snprintf returns the number of bytes stored in buffer, not counting
    the terminating null character. If the number of bytes required to
    store the data exceeds count, then count bytes of data are stored in
    buffer and a negative value is returned.

So -1 sounds Linux-specific.

Thank *you* for the opportunity to be thorough <wink>.
