*
* vsnprintf wrapper to provide ISO C99-compliant behavior.
*
* PARAMETERS:
* OUT s : The destination buffer. May be NULL if n is 0.
* If non-NULL, always NUL-terminated.
* IN n : The size of the destination buffer, measured in
* dropt_char-s.
* IN format : printf-style format specifier. Must not be NULL.
* IN args : Arguments to insert into the formatted string.
*
* RETURNS:
* The number of characters that would be written to the destination
* buffer if it's sufficiently large, excluding the NUL-terminator.
* Returns -1 on error.

*
* As far as I can tell, gcc's implementation of vsnprintf has always
* matched the behavior required by the C99 standard (which is to
* return the necessary buffer size).
*
* Note that this won't work with wchar_t because there is no true,
* standard wchar_t equivalent of snprintf. swprintf comes close but
* doesn't return the necessary buffer size (and the standard does not
* provide a guaranteed way to test if truncation occurred), and its
* format string can't be used interchangeably with snprintf.
*
* It's simpler not to support wchar_t on non-Windows platforms.
