    curs_inchstr(3x)                 Library calls                curs_inchstr(3x)

## NAME

           inchstr,   inchnstr,   winchstr,   winchnstr,   mvinchstr,  mvinchnstr,
           mvwinchstr, mvwinchnstr - get a curses character string from a 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).  Transfer stops at the end of the current line, or  when  n
           characters have been stored at the location referenced by chstr.

           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).

           X/Open Curses defines no error conditions.  This implementation returns
           an error

           o   if the win parameter is null or

           o   if the chstr parameter is null.

           Functions prefixed with "mv" first perform cursor movement and fail  if
           the position (y, x) is outside the window boundaries.

## NOTES

           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.

           Reading  a  line  that  overflows  the  array  pointed to by chstr with
           inchstr, mvinchstr, mvwinchstr or winchstr  causes  undefined  results.
           Therefore,  the  use of inchnstr, mvinchnstr, mvwinchnstr, or winchnstr
           is recommended.

## PORTABILITY

           These functions are described in X/Open Curses, 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.
