vwscanw - convert formatted input from a window
cc [ flag... ] file... –I /usr/xpg4/include –L /usr/xpg4/lib \ –R /usr/xpg4/lib –lcurses [ library... ] c89 [ flag... ] file... –lcurses [ library... ] #include <varargs.h> #include <curses.h> int vwscanw(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 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 >.
Upon successful completion, vwscanw() returns OK. Otherwise, it returns ERR.
No errors are defined.
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.
