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

SYNOPSIS
       #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
       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 (typi-
       cally a left motion).

RETURN VALUE
       All routines return the integer ERR upon failure and an OK (SVr4 specifies only "an integer value other than ERR") upon successful  comple-
       tion.

       X/Open defines no error conditions.

       In this implementation, these functions return an error if the window pointer is null, or if its timeout expires without having any data.

       This implementation provides an extension as well.  If a SIGWINCH interrupts the function, it will return KEY_RESIZE rather than OK or ERR.

       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 getstr, mvgetstr, and mvwgetstr may be macros.

PORTABILITY
       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.
