inchstr(3NCURSES)                                            inchstr(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(3NCURS-
       ES)].

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).

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

NOTES
       Note  that  all routines except winchnstr may be macros.  SVr4 does not
       document whether the result string is 0-terminated; it does  not  docu-
       ment  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.

SEE ALSO
       ncurses(3NCURSES), inch(3NCURSES).

       Comparable functions in the wide-character (ncursesw) library  are  de-
       scribed in in_wchstr(3NCURSES).

                                                             inchstr(3NCURSES)
