NAME

       vwprintf, vfwprintf, vswprintf -  Prints formatted output for wide characters from stdarg parameter list

LIBRARY

       Standard C Library (libc)

SYNOPSIS

       #include <stdarg.h> #include <stdio.h> #include <wchar.h>

       int vwprintf(
	       const wchar_t *format,
	       va_list printarg);

       int vfwprintf(
	       FILE *stream,
	       const wchar_t *format,
	       va_list printarg;

       int vswprintf(
	       wchar_t *wstr,
	       size_t n,
	       const wchar_t *format,
	       va_list printarg);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       vfwprintf(), vswprintf(), vwprintf():  XSH5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Specifies a wide-character string that combines literal characters with conversion specifications.  Specifies the arguments to be converted
       using the format parameter.  Points to a FILE structure specifying an open stream to which converted values are written.  Points to a char-
       acter  array  in  which the converted values are stored.  Specifies the maximum number of output wide characters, including the terminating
       null wide character.  Unless n is zero, a terminating null wide character is always added to output.

DESCRIPTION

       The vwprintf(), vfwprintf(), and vswprintf() functions convert, format, and write stdarg parameter lists.

       These functions are the same as the wprintf(), fwprintf(), and swprintf() functions, respectively, except these functions  are  not  called
       with a variable number of values.  Instead, vwprintf(), vfwprintf(), and vswprintf() are called with a parameter list pointer as defined by
       the stdarg.h header file.  Refer to the wprintf(3) reference page for information  about  conversion  specifications,  return  values,  and
       errors. Refer to the varargs(3) reference page for information about handling parameter lists.

NAME

       vfwprintf, vswprintf, vwprintf - wide-character formatted output of a stdarg argument list

SYNOPSIS

       #include <stdarg.h>
       #include <stdio.h>
       #include <wchar.h>

       int vfwprintf(FILE *restrict stream, const wchar_t *restrict format,
	    va_list arg);

       int vswprintf(wchar_t *restrict s, size_t n,
	    const wchar_t *restrict format, va_list arg);

       int vwprintf(const wchar_t *restrict format, va_list arg);

DESCRIPTION

       The  vwprintf(),  vfwprintf(),  and  vswprintf()  functions are the same as wprintf(), fwprintf(), and swprintf() respectively, except that
       instead of being called with a variable number of arguments, they are called with an argument list as defined by  <stdarg.h>.

       These functions do not invoke the  va_end() macro.  However, as these functions do invoke the va_arg() macro, the value	of  ap	after  the
       return is indeterminate.

RETURN VALUES

       Refer to  fwprintf(3C).

ERRORS

       Refer to  fwprintf(3C).

USAGE

       Applications using these functions should call va_end(ap) afterwards to clean up.

ATTRIBUTES

NOTES

       The  vwprintf(),  vfwprintf(),  and vswprintf() functions can be used safely in multithreaded applications, as long as setlocale(3C) is not
       being called to change the locale.
