The
vfwscanf(),
vswscanf(), and
vwscanf() functions shall
be equivalent to the
fwscanf(),
swscanf(), and
wscanf()
functions, respectively, except that instead of being called with a variable
number of arguments, they are called with an argument list as defined in the
<stdarg.h> header. These functions shall not invoke the
va_end macro. As these functions invoke the
va_arg macro, the
value of
ap after the return is unspecified.
Refer to
fwscanf() .
Refer to
fwscanf() .
The following sections are informative.
None.
Applications using these functions should call
va_end(
ap)
afterwards to clean up.
None.
