source: trunk/gtk/util.h @ 242

Last change on this file since 242 was 242, checked in by joshe, 16 years ago

Add IPC code for another process to communicate with a running

transmission-gtk instance.

Try to add any filenames found on the command-line, using IPC if

transmission-gtk is already running.

Some minor code cleanups.
Remove lockfile on a normal exit, justfor the sake of being tidy.
