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.
