+ int wgetstr(WINDOW *win, char *str);
+ 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 *win, int y, int x, char *str, int n);
+
+ int get_wstr(wint_t *wstr);
+ int wget_wstr(WINDOW *win, wint_t *wstr);
+ int mvget_wstr(int y, int x, wint_t *wstr);
+ int mvwget_wstr(WINDOW *win, int, int, wint_t *wstr);
+ int getn_wstr(wint_t *wstr, int n);
+ int wgetn_wstr(WINDOW *win, wint_t *wstr, int n);

+ int mvwgetn_wstr(WINDOW *win, int y, int x, wint_t *wstr, int n);
+
+ Description:
+ These routines call wgetch() repeatedly to build a string,
+ interpreting erase and kill characters along the way, until a
+ newline or carriage return is received. When PDCurses is built
+ with wide-character support enabled, the narrow-character
+ functions convert the wgetch()'d values into a multibyte string
+ in the current locale before returning it. The resulting string
+ is placed in the area pointed to by *str. The routines with n as
+ the last argument read at most n characters.
+
+ Note that there's no way to know how long the buffer passed to
+ wgetstr() is, so use wgetnstr() to avoid buffer overflows.
+
+ Return Value:
+ This functions return ERR on failure or any other value on
+ success.
