       getstr,	getnstr,  wgetstr,  wgetnstr,  mvgetstr, mvgetnstr, mvwgetstr,
       mvwgetnstr - accept character strings from curses terminal keyboard

SYNOPSIS    [Toc]    [Back]

       #include <curses.h>

       int getstr(char *str);
       int getnstr(char *str, int n);
       int wgetstr(WINDOW *win, char *str);
       int wgetnstr(WINDOW *win, char *str, int n);
       int mvgetstr(int y, int x, char *str);
       int mvwgetstr(WINDOW *win, int y, int x, char *str);
       int mvgetnstr(int y, int x, char *str, int n);
       int mvwgetnstr(WINDOW *, int y, int x, char *str, int n);

DESCRIPTION    [Toc]    [Back]

       The function getstr is equivalent to a series of calls to getch,  until
       a  newline or carriage return is received (the terminating character is
       not included in the returned string).  The resulting value is placed in
       the area pointed to by the character pointer str.

       wgetnstr  reads	at most n characters, thus preventing a possible overflow
 of the input buffer.  Any attempt to enter more characters	(other
       than  the terminating newline or carriage return) causes a beep.  Function
 keys also cause a beep and	are  ignored.	The  getnstr  function
       reads from the stdscr default window.

       The  user's  erase and kill characters are interpreted.	If keypad mode
       is on for the window, KEY_LEFT and KEY_BACKSPACE  are  both  considered
       equivalent to the user's kill character.

       Characters  input  are  echoed  only  if echo is currently on.  In that
       case, backspace is echoed as deletion of the previous character	(typically
 a left motion).

RETURN VALUE    [Toc]    [Back]

       All routines return the integer ERR upon failure and an OK (SVr4 specifies
 only "an integer value other than ERR")  upon  successful  completion.

NOTES    [Toc]    [Back]

       Note that getstr, mvgetstr, and mvwgetstr may be macros.

PORTABILITY    [Toc]    [Back]

       These  functions  are  described  in  the XSI Curses standard, Issue 4.
       They read single-byte characters only.  The standard  does  not	define
       any  error  conditions.	 This implementation returns ERR if the window
       pointer is null, or if the lower-level wgetch call returns an ERR.

       SVr3 and early SVr4 curses  implementations  did  not  reject  function
       keys;  the  SVr4.0  documentation  claimed that "special keys" (such as
       function keys, "home" key, "clear" key, etc.) are interpreted"  without
       giving  details.   It lied.  In fact, the `character' value appended to
       the string by those implementations  was  predictable  but  not	useful
       (being, in fact, the low-order eight bits of the key's KEY_ value).

       The  functions  getnstr, mvgetnstr, and mvwgetnstr were present but not
       documented in SVr4.
