Hi Samuel, I have used a loop for the non-blocking read in a thread at interval (300 millisec) and writing simultaneously. It worked. But it consumes a lot of CPU. So I noticed the following (See REFERENCE below). With the file descriptor returned in BRLTTY-windows (which is an attribute in the brlapi_handle_t) is it possible to do some thing similar in WIndows. Basically I am looking for a call back implementation in Windows. Any suggestion is helpful. Basically I am looking for any alternate to the equivalent of " (brlapi_readKey(1, &key)" call.
Thanks, Siju Samuel REFERENCE INFORMATION http://mielke.cc/brltty/doc/BrlAPIref/group__brlapi__keys.html Else, you'll probably want to use the file descriptor returned by *brlapi_openConnection()*<http://mielke.cc/brltty/doc/BrlAPIref/group__brlapi__connection.html#gacd26dc42640bdad09a389be10b9e3618>in your "big polling loop". For instance: - in a select() loop, just add it to the readfds and exceptfds file descriptor sets; - in a gtk or atspi application, use g_io_add_watch(fileDescriptor, G_IO_IN|G_IO_ERR|G_IO_HUP, f, data) for adding a callback called f; - in an Xt/Xaw/motif-based application, use XtAppAddInput(app_context, fileDescriptor, XtInputReadMask|XtInputExceptMask, f, data) - etc. and then, when you detect inbound trafic on the file descriptor, do something like this: while (brlapi_readKey(0, &code) { // process keycode code // ... } On Sat, Dec 14, 2013 at 12:10 PM, Samuel Thibault < samuel.thiba...@ens-lyon.org> wrote: > Siju Samuel, le Sat 14 Dec 2013 07:10:20 -0600, a écrit : > > Can I expect this will be fixed soon. > > When I get time, which is somehow undefined. > > > Also a related question; is this specific to the driver (device) or > > common code. > > It is common code. > > > As a resolution, is it good to perform non-bocking read at specific > intervals. > > So that read and write can be performed. > > That might help indeed. > > Samuel > _______________________________________________ > This message was sent via the BRLTTY mailing list. > To post a message, send an e-mail to: BRLTTY@mielke.cc > For general information, go to: http://mielke.cc/mailman/listinfo/brltty >
