vswscanf()

Updated: May 06, 2022

Scan input from a wide-character string (varargs)

Synopsis:

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

int vswscanf( const wchar_t * ws,
              const wchar_t * format,
              va_list arg );

Arguments:

ws
The wide-character string that you want to read from.
format
A wide-character string that specifies the format of the input. For more information, see scanf(). The formatting string determines what additional arguments you need to provide.
arg
A variable-argument list of the additional arguments, which you must have initialized with the va_start() macro.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The vswscanf() function scans input from the string designated by ws, under control of the argument format.

The vswscanf() function is the wide-character version of vsscanf(), and is a “varargs” version of swscanf().

Returns:

The number of input arguments for which values were successfully scanned and stored is returned, or EOF when the scanning is terminated by reaching the end of the input string.
