   * Name: tcgetattr
   *
   * Descripton:
   *   The tcgetattr() function gets the parameters associated with the
   *   terminal referred to by 'fd' and stores them in the termios structure
   *   referenced by 'termiosp'.
   *
   * Input Parameters:
   *   fd - The 'fd' argument is an open file descriptor associated with a terminal.
   *   termiosp - The termiosp argument is a pointer to a termios structure.
   *
   * Returned Value:
   *   Upon successful completion, 0 is returned. Otherwise, -1 is returned and
   *   errno is set to indicate the error.  The following errors may be reported:
   *
   *   - EBADF: The 'fd' argument is not a valid file descriptor.
   *   - ENOTTY: The file associated with 'fd' is not a terminal.
   *
