Reads input from the stream under control of the wide-character
int vswscanf (wchar_t *s, const wchar_t *format, va_list arg);
A pointer to a wide-character string from which the input is to
A pointer to a wide-character string containing the format
A list of expressions whose results correspond to conversion
specifications given in the format specification.
This function is equivalent to the swscanf function, except that
instead of being called with a variable number of arguments, it
is called with an argument list (arg) that has been initialized
by va_start (and possibly with subsequent va_arg calls).
The vswscanf function is also equivalent to the vfwscanf
function, except that the first argument specifies a wide-
character string rather than a stream. Reaching the end of the
wide-character string is the same as encountering EOF for the
Also see vfwscanf and swscanf.

and their corresponding arguments, see the "Understanding Input
and Output" chapter of the Compaq C Run-Time Library Reference
Manual for OpenVMS Systems.
n The number of wide characters read.
EOF Indicates that a read error occurred before
any conversion. The function sets errno. For a
list of the values set by this function, see
