Several users of the signal API used custom convenience classes to invoke signal-handling functions on the reception of incoming signals. The 'Signal_dispatcher' pattern turned out to be particularly useful. To avoid the duplication of this code across the code base, this patch adds the interface to 'base/signal.h'. Furthermore, the patch changes the 'Signal::num()' return type from int to unsigned because negative numbers are meaningless here. Fixes #511
This is the example operating system based on the Genode OS framework: :_Init_: is the first real process in the system. The provided implementation uses a very simple XML parser to read its configuration files. :_Drivers_: The example OS has basic drivers for frame buffer, mouse and keyboard input, the PCI bus, the real-time clock, and system-specific timers. :_Server_: The only server in the example OS is Nitpicker, a minimal-complexity GUI server. :_Test_: are also part of the example OS. You may have a look at the fork bomb as a simple system stress test. :_Ldso_: is the dynamic linker used for loading executables that are linked against shared libraries. :_Lib_: contains libraries used by the components of the OS repository, in particular the device-driver kit, the alarm framework, and support for dynamic linking.
