ANSI Error Message Function

void warnx(const char *format, ...);

Internationalization (I18n) Function Overview

The warnx function is closely related to both the error and warn functions.

Its roughly equivalent to a call like error(status, 0, format, ...), except that the global variable error is not used and no error number string is printed.

Its also the same as the warn function except that no error number string is printed. Note that this feature distinguishes warnx from warn in that it does not have the embedded English error text problem, and therefore is more safe for internationalized applications.

I18n Issues

Prior to calling this function, ensure that the current locale is set properly by calling setlocale, as string formatting is dependent on the LC_NUMERIC locale category. See String Formatting in C and C++ for a discussion on locale-sensitive formatting in internationalized applications.

There is no ANSI wide character version of this function. The parameters will have to be converted to multibyte UTF-8 characters and then the warnx function can be used.

Recommended Replacements*

ANSI UTF-8	warnx
ANSI UTF-16	convert and use warnx
