This also disables +// all of the thread safety support on platforms where it is +// available. +// +// SIGSLOT_USE_POSIX_THREADS - Force use of Posix threads when using a C++ compiler other than +// gcc on a platform that supports Posix threads. (When using gcc, +// this is the default - use SIGSLOT_PURE_ISO to disable this if +// necessary) +// +// SIGSLOT_DEFAULT_MT_POLICY - Where thread support is enabled, this defaults to multi_threaded_global. +// Otherwise, the default is single_threaded. #define this yourself to +// override the default. In pure ISO mode, anything other than +// single_threaded will cause a compiler error. +// +// PLATFORM NOTES +// +// Win32 - On Win32, the WIN32 symbol must be #defined. Most mainstream +// compilers do this by default, but you may need to define it +// yourself if your build environment is less standard. This causes +// the Win32 thread support to be compiled in and used automatically. +// +// Unix/Linux/BSD, etc. - If you're using gcc, it is assumed that you have Posix threads +// available, so they are used automatically. You can override this +// (as under Windows) with the SIGSLOT_PURE_ISO switch. If you're using +// something other than gcc but still want to use Posix threads, you +// need to #define SIGSLOT_USE_POSIX_THREADS. +// +// ISO C++ - If none of the supported platforms are detected, or if +// SIGSLOT_PURE_ISO is defined, all multithreading support is turned off, +// along with any code that might cause a pure ISO C++ environment to +// complain. Before you ask, gcc -ansi -pedantic won't compile this +// library, but gcc -ansi is fine. Pedantic mode seems to throw a lot of +// errors that aren't really there. If you feel like investigating this, +// please contact the author. +// +// +// THREADING MODES +// +// single_threaded - Your program is assumed to be single threaded from the point of view +// of signal/slot usage (i.e. all objects using signals and slots are +// created and destroyed from a single thread). Behaviour if objects are +// destroyed concurrently is undefined (i.e. you'll get the occasional +// segmentation fault/memory exception). +// +// multi_threaded_global - Your program is assumed to be multi threaded. Objects using signals and +// slots can be safely created and destroyed from any thread, even when +// connections exist. In multi_threaded_global mode, this is achieved by a +// single global mutex (actually a critical section on Windows because they +// are faster). This option uses less OS resources, but results in more +// opportunities for contention, possibly resulting in more context switches +// than are strictly necessary. +// +// multi_threaded_local - Behaviour in this mode is essentially the same as multi_threaded_global, +// except that each signal, and each object that inherits has_slots, all +// have their own mutex/critical section. In practice, this means that +// mutex collisions (and hence context switches) only happen if they are +// absolutely essential. However, on some platforms, creating a lot of +// mutexes can slow down the whole OS, so use this option with care. +// +// USING THE LIBRARY +// +// See the full documentation at http://sigslot.sourceforge.net/ +// +// + +#ifndef __SIGSLOT_H__ +#define __SIGSLOT_H__ + +#include +#include + +#if defined(SIGSLOT_PURE_ISO) || (!defined(WIN32) && !defined(__GNUG__) && !defined(SIGSLOT_USE_POSIX_THREADS)) +# define _SIGSLOT_SINGLE_THREADED +#elif defined(WIN32) +# define _SIGSLOT_HAS_WIN32_THREADS +# include +#elif defined(__GNUG__) || defined(SIGSLOT_USE_POSIX_THREADS) +# define _SIGSLOT_HAS_POSIX_THREADS +# include +#else +# define _SIGSLOT_SINGLE_THREADED +#endif + +#ifndef SIGSLOT_DEFAULT_MT_POLICY +# ifdef _SIGSLOT_SINGLE_THREADED +# define SIGSLOT_DEFAULT_MT_POLICY single_threaded +# else +# define SIGSLOT_DEFAULT_MT_POLICY multi_threaded_local +# endif +#endif + +#ifndef SIGSLOT_EMIT +# ifdef QT_VERSION +# define SIGSLOT_EMIT broadcast +# else +# define SIGSLOT_EMIT emit +# endif +#endif + +namespace sigslot { + +class single_threaded +{ +public: + single_threaded() {} + virtual ~single_threaded() {} + virtual void lock() {} + virtual void unlock() {} +};
