curs_inchstr(3X)                                                                            curs_inchstr(3X)



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 curs_inch(3X)].

RETURN VALUE
       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.

NOTES
       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.

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

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