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
       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         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

       •   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
       using 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

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).
