SYNOPSIS
| |
#include <stdarg.h>
#include <curses.h> int vw_scanw(WINDOW *win, char *fmt, va_list varglist); |
| |

-
varglist
- Is a pointer to a list of parameters.
-
win
- Is a pointer to the window in which the character is to be read.

The vw_scanw() function achieves the same effect as wscanw(3XCURSES) using a variable argument list. The third argument is a va_list, as defined
in <stdarg.h>.
|
| |
Upon successful completion, vw_scanw() returns OK. Otherwise, it returns ERR.
|
| |
The vw_scanw() function is preferred over vwscanw(3XCURSES). 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.
