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
       (typically 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
       completion.

       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.

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.
