inchnstr(3ncurses)


NAME

   inchstr, inchnstr, winchstr, winchnstr, mvinchstr, mvinchnstr,
   mvwinchstr, mvwinchnstr - get a string of characters (and attributes)
   from a curses window

SYNOPSIS

   #include <curses.h>

   int inchstr(chtype *chstr);
   int inchnstr(chtype *chstr, int n);
   int winchstr(WINDOW *win, chtype *chstr);
   int winchnstr(WINDOW *win, chtype *chstr, int n);
   int mvinchstr(int y, int x, chtype *chstr);
   int mvinchnstr(int y, int x, chtype *chstr, int n);
   int mvwinchstr(WINDOW *win, int y, int x, chtype *chstr);
   int mvwinchnstr(WINDOW *win, int y, int x, chtype *chstr, int n);

DESCRIPTION

   These  routines  return  a  NULL-terminated array of chtype quantities,
   starting at the current cursor position in the named window and  ending
   at  the  right  margin of the window.  The four functions with n as the
   last argument, return a leading substring at  most  n  characters  long
   (exclusive of the trailing (chtype)0).  Constants defined in <curses.h>
   can be used with the & (logical AND) operator to extract the  character
   or   the   attribute   alone  from  any  position  in  the  chstr  [see
   inch(3NCURSES)].

RETURN VALUE

   All routines return the integer ERR upon failure and an  integer  value
   other  than  ERR  upon  successful completion (the number of characters
   retrieved, exclusive of the trailing 0).

   No error conditions are defined.  If the chstr parameter  is  null,  no
   data is returned, and the return value is zero.

   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.

NOTES

   Note  that  all routines except winchnstr may be macros.  SVr4 does not
   document whether the result string  is  zero-terminated;  it  does  not
   document  whether  a length limit argument includes any trailing 0; and
   it does not document the meaning of the return value.

PORTABILITY

   These functions are described in the XSI Curses standard, Issue 4.   It
   is  no more specific than the SVr4 documentation on the trailing 0.  It
   does specify that the successful return of the functions is OK.
