curs_inchstr(3X)								 curs_inchstr(3X)

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

       #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);

       These routines return a NULL-terminated array of chtype quantities, starting at	the  cur-
       rent  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 char-
       acters 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)].

       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).

       Note that all routines except winchnstr may be macros.  SVr4 does not document whether the
       result  string  is  0-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.

       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.

       curses(3X), curs_inch(3X).
