curs_inchstr(3X)                                        curs_inchstr(3X)

NAME         top

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

SYNOPSIS         top

       #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         top

       These  routines  return a NULL-terminated array of chtype quanti‐
       ties, 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) opera‐
       tor to extract the character or the attribute alone from any  po‐
       sition in the chstr [see curs_inch(3X)].

RETURN VALUE         top

       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).

       X/Open  Curses  defines no error conditions.  In this implementa‐
       tion:

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

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

       Functions with a “mv” prefix first perform a cursor movement us‐
       ing wmove, and return an error if the position is outside the
       window, or if the window pointer is null.

NOTES         top

       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         top

       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         top

       Comparable functions in the wide-character (ncursesw) library are
       described in curs_in_wchstr(3X).
