CURSES_PRINT(3) 					   BSD Library Functions Manual 					   CURSES_PRINT(3)

NAME

     curses_print, printw, wprintw, mvprintw, mvwprintw, unctrl -- curses print formatted strings on windows routines

LIBRARY

     Curses Library (libcurses, -lcurses)

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, ...);

     char *
     unctrl(chtype ch);

DESCRIPTION

     These functions print formatted strings on stdscr or on the specified window.

     The printw() function formats and prints its arguments on stdscr.	The behavior is deliberately similar to that of printf(3), but, notably,
     the return value differs.

     The wprintw() function is the same as the printw() function, excepting that the resulting output is printed on the window specified by win.

     The mvprintw() and mvwprintw() functions are the same as the printw() and wprintw() functions, respectively, excepting that wmove() is called
     to move the cursor to the position specified by y, x before the output is printed on the window.

     The unctrl() function returns a printable string representation of the character ch.  If ch is a control character then it will be converted
     to the form ^Y.

RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.  The functions that return an int will return one of the following
     values:

	   OK	The function completed successfully.

	   ERR	An error occurred in the function.

STANDARDS

     The NetBSD Curses library complies with the X/Open Curses specification, part of the Single Unix Specification.

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>.
