vwprintf(3) Library Functions Manual vwprintf(3)
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.
