curs_inchstr(3x)                                              curs_inchstr(3x)




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
       curs_inch(3x)].


RETURN VALUE

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

       X/Open Curses defines no error conditions.  In this implementation:

       o   If the win parameter is null, an error is returned,

       o   If the chstr parameter is null, an error is returned,

       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 doc-
       ument 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.
