int vw_scanw(WINDOW *win, char *fmt, va_list varglist);

Is a scanf() format string.


Is a pointer to a list of parameters.


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.

No errors are defined.

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.
