It isn't correct (non C99 compliant snprintf will return -1).

    char buf[] = {0, 0, 0, 0};

is fully C compliant.

I managed to add a good GPL compatible snprintf implementation. It provides
snprintf/vsnprintf/asprintf/vasprintf implementation. The snprintf/vsnprintf
implementation is ISO C99 compliant. It will _always_ terminate the output
string, so everyone can rely on it.
