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).

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

       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 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).
