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 completion.

       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.

       Functions with a "mv" prefix first perform a cursor movement using wmove, and  return  an  error  if  the
       position is outside the window, or 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       WITHDRAWN, and is to be replaced by a function vw_printw using the 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 vwprintw 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>.
