Detailed Description

Implements the classic ``test and set'' operation.

This class keeps track of the status of <is_set_>, which can be
set based on various events (such as receipt of a signal).
This class is derived from ACE_Event_Handler so that it can be
"signaled" by a Reactor when a signal occurs.  We assume that
<TYPE> is a data type that can be assigned the value 0 or 1.

*/ template <class ACE_LOCK, class TYPE> class ACE_Test_and_Set : public ACE_Event_Handler { public: ACE_Test_and_Set (TYPE initial_value = 0);

/ Returns true if we are set, else false. TYPE is_set () const;

/ Sets the <is_set_> status, returning the original value of / <is_set_>. TYPE set (TYPE);

/ Called when object is signaled by OS (either via UNIX signals or / when a Win32 object becomes signaled). virtual int handle_signal (int signum, siginfo_t * = 0, ucontext_t * = 0);

private: / Keeps track of our state. TYPE is_set_;

/ Protect the state from race conditions. ACE_LOCK lock_; };
