(mouse_aware): Enable detection of additional mouse events for select(). Tune function to precisely match actual reporting criteria. Move adjustment of mouse position (by window scroll offset) here to avoid duplicate code. (char_command): Initialization of enhanced mouse reporting modes. Initialization of focus reporting mode. * fhandler.h (use_mouse): Change flag (bool->int) to indicate additional mouse modes. Add flag to indicate focus reporting. (mouse_aware): Move enhanced function into fhandler_console.cc. * select.cc (peek_console): Use modified mouse_aware() for more general detection of mouse events. Also check for focus reports.
* * select.cc (peek_console): Always check window size when there is ANY keyboardChristopher Faylor2009-09-011-1/+1

(_cygtls::init_thread): Drop initalizing of sockevt to INVALID_HANDLE_VALUE. (_cygtls::fixup_after_fork): Reset sockevt to NULL. (_cygtls::remove): Don't use sockevt value to bail out prematurely. Set sockevt to NULL. Free malloced select members. * select.h (struct select_socket_info): Drop max_w4 member. * select.cc (thread_socket): Use INFINITE timeout value if number of objects to wait for is <= MAXIMUM_WAIT_OBJECTS. Use num_w4 member of select_socket_info struct rather than dropped max_w4. (init_tls_select_info): New inline function to initialize TLS select members. (start_thread_socket): Just call init_tls_select_info to initialize TLS select members and use them later on. (socket_cleanup): Don't free select_socket_info pointer members since they are thread local now.
