_get_printf_count_output
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.
The latest version of this topic can be found at _get_printf_count_output.
Indicates whether printf, _printf_l, wprintf, _wprintf_l-family functions support the %n
format.
Syntax
int _get_printf_count_output();
Return Value
Non-zero if %n
is supported, 0 if %n
is not supported.
Remarks
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.
