/* Convenient macro for testing for deadlock, as well as for detecting
* when mutexes fail.
*
* The parameters to the ACE_GUARD_XXX macros are used as follows:
*
* MUTEX - This is the type used as the template parameter for ACE_Guard
*
* OBJ - Name for the guard object. This name should not be declared
* outside the macro.
*
* LOCK - The actual lock (mutex) variable. This should be a variable
* of type MUTEX, see above.
*
* ACTION - Code segment to be run, if and only if the lock is
* acquired.
*
* REACTION - Code segment to be run, if and only if the lock is not
* acquired.
*
* RETURN - A value to be returned from the calling function, if and
* only if the lock is not acquired.
*
* @warning
* Use of ACE_GUARD() is rarely correct. ACE_GUARD() causes the
* current function to return if the lock is not acquired. Since
* merely returning (no value) almost certainly fails to handle the
* acquisition failure and almost certainly fails to communicate the
* failure to the caller for the caller to handle, ACE_GUARD() is
* almost always the wrong thing to do. The same goes for
* ACE_WRITE_GUARD() and ACE_READ_GUARD() . ACE_GUARD_REACTION() is
* better because it lets you specify error handling code.

*
* More details about this component are available in the documentation

/**
* For service classes scoped within namespaces, use this macro in
* place of ACE_FACTORY_DEFINE. The third argument in this case is
* the fully scoped name of the class as it is to be
* instantiated. For example, given:
* namespace ACE
* {
* namespace Foo
* {
* class Bar : public ACE_Service_Object
* {};
* };
* };
*
* ACE_FACTORY_DECLARE(ACE,ACE_Foo_Bar)
*
* you would then use:
*
* ACE_FACTORY_NAMESPACE_DEFINE(ACE,ACE_Foo_Bar,ACE::Foo::Bar)
*
* Note that in this example, the ACE_FACTORY_DECLARE is done outside
* the namespace scope. Then, the SERVICE_CLASS name is the same as
* the fully scoped class name, but with '::' replaced with '_'. Doing
* this will ensure unique generated signatures for the various C
* style functions.
