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(3NCURSES)].

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).

       X/Open Curses defines no error conditions.  In this implementation:

       •   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

       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

       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.
