  Name:                                                         termattr

  Synopsis:
        int baudrate(void);
        char erasechar(void);
        bool has_ic(void);
        bool has_il(void);
        char killchar(void);
        char *longname(void);
        chtype termattrs(void);
        attr_t term_attrs(void);
        char *termname(void);

        int erasewchar(wchar_t *ch);
        int killwchar(wchar_t *ch);

        char wordchar(void);

  Description:
        baudrate() is supposed to return the output speed of the
        terminal. In PDCurses, it simply returns INT_MAX.

        has_ic and has_il() return TRUE. These functions have meaning in
        some other implementations of curses.

        erasechar() and killchar() return ^H and ^U, respectively -- the
        ERASE and KILL characters. In other curses implementations,
        these may vary by terminal type. erasewchar() and killwchar()
        are the wide-character versions; they take a pointer to a
        location in which to store the character, and return OK or ERR.

        longname() returns a pointer to a static area containing a
        verbose description of the current terminal. The maximum length
        of the string is 128 characters.  It is defined only after the
        call to initscr() or newterm().

        termname() returns a pointer to a static area containing a
        short description of the current terminal (14 characters).

        termattrs() returns a logical OR of all video attributes
        supported by the terminal.

        wordchar() is a PDCurses extension of the concept behind the
        functions erasechar() and killchar(), returning the "delete
        word" character, ^W.
