ANSI Error Message Function

void errx(int status, const char *format, ...);

Internationalization (I18n) Function Overview

The errx function is closely related to both the error and err functions.

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

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

I18n Issues

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 errx function can be used.

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.

Recommended Replacements*

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