_get_printf_count_output 

Indicates whether printf, _printf_l, wprintf, _wprintf_l-family functions support the %n format.


int _get_printf_count_output();

Non-zero if %n is supported, 0 if %n is not supported.

If %n is not supported (the default), encountering %n in the format string of any of the printf functions will invoke the invalid parameter handler as described in Parameter Validation. If %n support is enabled (see _set_printf_count_output) then %n will behave as described in printf Type Field Characters.
