NAME
curs_printw, printw, wprintw, mvprintw, mvwprintw, vw_printw, vwprintw - 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 <stdarg.h> include <curses.h> int vw_printw( WINDOW *win, char *fmt, va_list varglist ); #include <varargs.h> include <curses.h> int vwprintw( WINDOW *win, char *fmt, va_list varglist ); LIBRARY
Curses Library (libcurses) STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: printw, wprintw, mvprintw, mvwprintw, vw_printw, vwprintw: XCURSES4.2 Refer to the standards(5) reference page for more information about industry standards and associated tags. DESCRIPTION
The printw, wprintw, mvprintw, and mvwprintw routines are analogous to printf family of routines (see printf(3)). In effect, the printw routines output the string that would be output by printf as though waddstr were used on the given window. The vw_printw routine is analogous to vprintf (see vprintf(3)) and performs the same operation as wprintw but uses a variable argument list. The va_list type is a pointer to a list of arguments and is defined in <stdarg.h>. The vwprintw routine is equivalent to vw_printw except that va_list is defined in <varargs.h>. The vw_printw routine is recommended for use in new applications. NOTES
The header file <curses.h> automatically includes the header file <stdio.h>. RETURN VALUES
All routines return the integer ERR upon failure and OK upon successful completion. SEE ALSO

NAME
printw, wprintw, mvprintw, mvwprintw, vwprintw, vw_printw - print formatted output in curses windows SYNOPSIS
#include <curses.h> int printw(const char *fmt, ...); int wprintw(WINDOW *win, const char *fmt, ...); int mvprintw(int y, int x, const char *fmt, ...); int mvwprintw(WINDOW *win, int y, int x, const char *fmt, ...); int vwprintw(WINDOW *win, const char *fmt, va_list varglist); int vw_printw(WINDOW *win, const char *fmt, va_list varglist); DESCRIPTION
The printw, wprintw, mvprintw and mvwprintw routines are analogous to printf [see printf(3)]. In effect, the string that would be output by printf is output instead as though waddstr were used on the given window. The vwprintw and wv_printw routines are analogous to vprintf [see printf(3)] and perform a wprintw using a variable argument list. The third argument is a va_list, a pointer to a list of arguments, as defined in <stdarg.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 com- pletion. X/Open defines no error conditions. In this implementation, an error may be returned if it cannot allocate enough memory for the buffer used to format the results. It will return an error if the window pointer is null. 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. The Single Unix Specification, Version 2 states that vw_printw is preferred to vw- printw since the latter requires including <varargs.h>, which cannot be used in the same file as <stdarg.h>. This implementation uses <stdarg.h> for both, because that header is included in <curses.h>. SEE ALSO
