String Format Function

int vasprintf(char **ptr, const char *template, va_list ap);

Internationalization (I18n) Function Overview

The vasprintf function is similar to asprintf, except that instead of taking a variable number of arguments directly, it takes an argument list pointer ap of type va_list.

I18n Issues

Prior to calling one of these functions, 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 vasprintf function can be used.

Recommended Replacements*

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