From mboxrd@z Thu Jan 1 00:00:00 1970 From: Steve Tell To: Guile-GTK List , Guile Mailing List Subject: select+read on socket in gtk,guile-gtk Date: Mon, 19 Jun 2000 20:17:00 -0000 Message-id: X-SW-Source: 2000-q2/msg00059.html Does guile-gtk provide a way to hook (file descriptors from) guile ports into the Gtk+ select loop? Glib's GIOChannel's perhaps? I know I could fall back on gtk-idle-add, but it seems less clean. Next question then is, how do I do a non-blocking read on a guile port, returning as many characters as are available right now? Is there an interface to the raw read(2) system call, like perl's sysread()? What I'm ultimately trying to do is arrange for a procedure to get called with complete lines read from a connected TCP socket, so that information recieved from the server at the other end can be used to update a items in a guile-gtk interface. In C its easy: fd = socket() conect(fd ... ) /* use my select, or hook into fd_set of another select() caller */ n = read(fd, rbuf, sizeof(rbuf)) /* scan buffer, looking for newlines. When a whole line is found, dispatch to line-parsing function. Save partial lines for next time around */ I've already built a version of this in C hooked to guile for an app that already has extensive C routines linked in, but I'd rather do a little desk-widget companion in pure guile-gtk if possible. Guile already has all of the the socket operations, so I suspect I'm just overlooking somthing. thanks, Steve steve@telltronics.org
