Member Function Documentation

Mword Keyb::get_attributes (   )  const [virtual]

Console attributes. Reimplemented from Console.

int Keyb::getchar (  bool  blocking = true  )  [virtual]

read a charcater from the input. Parameters: blocking  if true getchar blocks til a charcater is available. This method must be implemented in every implementation, but can simply return -1 for output only consoles. Reimplemented from Console.

int Keyb::write (  char const *  str, size_t  len )  [virtual]

Write a string of len chacters to the output. Parameters: str  the string to write (no zero termination is needed) len  the number of chacters to write. This method must be implemented in every implementation, but can simply do nothing for input only consoles. Reimplemented from Console.
