int vwscanw(
WINDOW *win,
char *fmt,
va_list varglist);
PARAMETERS
fmt Is a
scanf() format string.
varglist Is a pointer to a list of parameters.
win Is a pointer to the window in which the character is to
be read.
DESCRIPTION
The
vwscanw() function achieves the same effect as
wscanw(3XCURSES) using a variable argument list. The third argument is a
va_list, as
defined in <
varargs.h>.
RETURN VALUES
Upon successful completion,
vwscanw() returns
OK. Otherwise, it
returns
ERR.
ERRORS
No errors are defined.
USAGE
The
vwscanw() function is deprecated; the
vw_scanw(3XCURSES) function
is preferred. The use of the
vwscanw() and
vw_scanw() in the same
file will not work, due to the requirements to include <
varargs.h>
and <
stdarg.h>, which both contain definitions of
va_list.
