NAME

vprintf, vfprintf, vsprintf − print formatted output of a variable argument list

SYNOPSIS

#include <stdio.h>
#include <stdarg.h>
#include <widec.h> int vprintf (const char ∗format, va_list ap); int vfprintf (FILE ∗stream, const char ∗format, va_list ap); int vsprintf (char ∗s, const char ∗format, va_list ap);

DESCRIPTION (International Functions)

vprintf(), vfprint(), and vsprintf() are the same as printf(), fprintf(), and sprintf() respectively, except that instead of being called with a variable number of arguments, they are called with an argument list as defined by the <stdarg.h> header file. 

wc and ws are the new conversion specifications for wchar_t character control.  Both wc and ws may be used in all three functions. 

wc The wchar_t character arg is transformed into EUC, and then printed.  If a field width is specified and the transformed EUC has fewer bytes than the field width, it will by padded to the given width.  A precision specification is ignored, if specified. 

ws The arg is taken to be a wchar_t string and the wchar_t characters from the string are transformed into EUC, and printed until a wchar_t null character is encountered or the number of bytes indicated by the precision specification is printed.  If the precision specification is missing, it is taken to be infinite, and all wchar_t characters up to the first wchar_t null character are transformed into EUC and printed.  If a field width is specified and the transformed EUC have fewer bytes than the field width, they are padded to the given width. 

The ASCII space character (0x20) is used as a padding characters.
