curs_printw(3)
NAME
printw, wprintw, mvprintw, mvwprintw, vwprintw, vw_printw
- print formatted output in curses windows
SYNOPSIS
#include <curses.h> int printw(char *fmt [, arg] ...); int wprintw(WINDOW *win, char *fmt [, arg] ...); int mvprintw(int y, int x, char *fmt [, arg] ...); int mvwprintw(WINDOW *win, int y, int x, char *fmt [, arg] ...); #include <varargs.h> int vwprintw(WINDOW *win, char *fmt, varglist); int vw_printw(WINDOW *win, char *fmt, varglist);
DESCRIPTION
The printw, wprintw, mvprintw and mvwprintw routines are
analogous to printf [see printf(3S)]. In effect, the
string that would be output by printf is output instead as
though waddstr were used on the given window.
The vwprintw routine is analogous to vprintf [see
printf(3S)] and performs a wprintw using a variable argument list. The third argument is a va_list, a pointer to
a list of arguments, as defined in <varargs.h>.
RETURN VALUE
Routines that return an integer return ERR upon failure
and OK (SVr4 only specifies "an integer value other than
ERR") upon successful completion.
PORTABILITY
The XSI Curses standard, Issue 4 describes these functions. The function vwprintw is marked TO BE WITHDRAWN,
and is to be replaced by a function vw_printw using the
<stdarg.h> interface.
