scanw, wscanw, mvscanw, mvwscanw, vwscanw, vw_scanw - convert formatted input from a curses window #include <curses.h> int scanw(char *fmt [, arg] ...);

int wscanw(WINDOW *win, char *fmt [, arg] ...);

int mvscanw(int y, int x, char *fmt [, arg] ...);

int mvwscanw(WINDOW *win, int y, int x, char *fmt [, arg] ...);

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

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

The scanw, wscanw and mvscanw routines are analogous to scanf [see scanf(3S)]. The effect of these routines is as though wgetstr were called on the window, and the resulting line used as input for sscanf(3). Fields which do not map to a variable in the fmt field are lost. The vwscanw routine is similar to vwprintw in that it performs a wscanw using a variable argument list. The third argument is a va_list, a pointer to a list of arguments, as defined in <varargs.h>. vwscanw returns ERR on failure and an integer equal to the number of fields scanned on success. Applications may use the return value from the scanw, wscanw, mvscanw and mvwscanw routines to determine the number of fields which were mapped in the call. The XSI Curses standard, Issue 4 describes these functions. The function vwscanw is marked TO BE WITHDRAWN, and is to be replaced by a function vw_scanw using the <stdarg.h> interface. curses(3X), curs_getstr(3X), curs_printw(3X), scanf(3S) #
