void cfg_window_size::set_data_raw ( stream_reader *  p_stream, t_size  p_sizehint, abort_callback &  p_abort  )

virtual

Sets state of the variable. Called only from main thread, when reading configuration file.

Parameters

p_stream	Stream containing new state of the variable.
p_sizehint	Number of bytes contained in the stream; reading past p_sizehint bytes will fail (EOF).

Implements cfg_var_reader.
