Writes formatted wide characters.
Standard C Library (libc.a)
#include <wchar.h> #include <stdarg.h>
int vwsprintf (wcs, Format, arg)
wchar_t * wcs;
const char * Format;
The vwsprintf subroutine writes formatted wide characters. It is structured like the vsprintf subroutine with a few differences. One difference is that the wcs parameter specifies a wide character array into which the generated output is to be written, rather than a character array. The second difference is that the meaning of the S conversion specifier is always the same in the case where the # flag is specified. If copying takes place between objects that overlap, the behavior is undefined.
|wcs||Specifies the array of wide characters where the output is to be written.|
|Format||Specifies a multibyte character sequence composed of zero or more directives (ordinary multibyte characters and conversion specifiers). The new formats added to handle the wide characters are:|
|arg||Specifies the parameters to be printed.|
The vwsprintf subroutine returns the number of wide characters (not including the terminating wide character null) written into the wide character array and specified by the wcs parameter.
This subroutine is part of Base Operating System (BOS) Runtime.
