Top Forums Programming sockets - can you send data while waiting on select() Post 302526473 by expl on Tuesday 31st of May 2011 03:33:23 PM

recv() is capable to timeout as it uses select syscall internally and timeout is configured with setsockopt(), putting one more select call in front just adds overhead.

dbus-cleanup-sockets(1) 				      General Commands Manual					   dbus-cleanup-sockets(1)

NAME
dbus-cleanup-sockets - clean up leftover sockets in a directory SYNOPSIS
dbus-cleanup-sockets [DIRECTORY] DESCRIPTION
The dbus-cleanup-sockets command cleans up unused D-Bus connection sockets. See http://www.freedesktop.org/software/dbus/ for more informa- tion about the big picture. If given no arguments, dbus-cleanup-sockets cleans up sockets in the standard default socket directory for the per-user-login-session mes- sage bus; this is usually /tmp. Optionally, you can pass a different directory on the command line. On Linux, this program is essentially useless, because D-Bus defaults to using "abstract sockets" that exist only in memory and don't have a corresponding file in /tmp. On most other flavors of UNIX, it's possible for the socket files to leak when programs using D-Bus exit abnormally or without closing their D-Bus connections. Thus, it might be interesting to run dbus-cleanup-sockets in a cron job to mop up any leaked sockets. Or you can just ignore the leaked sockets, they aren't really hurting anything, other than cluttering the output of "ls /tmp" AUTHOR
dbus-cleanup-sockets was adapted by Havoc Pennington from linc-cleanup-sockets written by Michael Meeks. BUGS
Please send bug reports to the D-Bus mailing list or bug tracker, see http://www.freedesktop.org/software/dbus/ dbus-cleanup-sockets(1)
