curs_scanw(3) Library Functions Manual curs_scanw(3) NAME curs_scanw, scanw, wscanw, mvscanw, mvwscanw, vw_scanw, vwscanw - Con- vert formatted input from a Curses window LIBRARY Curses Library (libcurses.a, libcurses.so) SYNOPSIS #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] ...); include <stdarg.h> include <curses.h> int vw_scanw(WINDOW *win, char *fmt, va_list varglist); include <varargs.h> include <curses.h> int vwscanw(WINDOW *win, char *fmt, va_list varglist); STANDARDS Interfaces documented on this reference page conform to industry stan- dards as follows: scanw, wscanw, mvscanw, mvwscanw, vw_scanw, vwscanw: XPG4-UNIX Refer to the standards(5) reference page for more information about in- dustry standards and associated tags. DESCRIPTION The scanw, wscanw, and mvscanw routines correspond to scanf (see fs- canf(3)). The effect of these routines is as though wgetstr were called on the window, and the resulting line were used as input for the scan. Fields that do not map to a variable in the fmt field are lost. The vw_scanw routine is similar to vwprintw in that it uses a variable argument list. The third argument is va_list, a pointer to a list of arguments, as defined in stdarg.h. The vwscanw routine is equivalent to vw_scanw except that va_list is defined in varargs.h. Use of vw_scanw is recommended for new applica- tions. NOTES The header file curses.h automatically includes the header file stdio.h. RETURN VALUES These routines return ERR on failure and OK upon successful completion.
