source: view.c @ 7803326

release-1.9
Last change on this file since 7803326 was f271129, checked in by Jason Gross <jgross@mit.edu>, 10 years ago
Fix up headers The additions to owl.h and some of the removals were done by Alejandro Sedeño <asedeno@mit.edu> in commit 77a0258b3919468fc9d7f7602588ac427ab36e6c. Notes: * I think owl.c lost the need for sys/time.h when we punted select() in favor of glib's main loop. * We don't actually need to include things like stdarg.h, stdio.h, glib/gstdio.h, glib-object.h. I think they get indirectly included via owl.h and/or glib.h. They're left in (or added in to) the files that use functions/types from them. * I'm not entirely sure what sys/socket.h is doing in message.c. It is there from the initial commit. I suspect it might have had something to do with the call to getnameinfo. message.c compiles without it, but http://pubs.opengroup.org/onlinepubs/009695399/functions/getnameinfo.html suggests that we're supposed to include it? *shrugs* I'm leaving it in, for now. (Rather, I'll leave one copy of the #include in.)
