Member Function Documentation

int Filter_console::char_avail ( ) const [virtual]

Is input available?
This method can be implemented. It must return -1 if no information is available, 1 if at least one character is avialable, and 0 if no charachter is available.
Reimplemented from Console.

Mword Filter_console::get_attributes ( ) const [virtual]

Console attributes.

Reimplemented from Console.

int Filter_console::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 Filter_console::getchar_timeout ( unsigned timeout ) [inline, private]

int Filter_console::write ( char const * str,

size_t len

) [virtual]

Write a string of len chacters to the output.
