#define _STATIC_MEM_POOL_TRACE	(	_Lck,
		_Msg		)	((void)0)

#define DECLARE_STATIC_MEM_POOL

(

_Cls

)

Value:

public: \
    static void* operator new(size_t size) \
    { \
        assert(size == sizeof(_Cls)); \
        void* ptr; \
        ptr = NVWA::static_mem_pool<sizeof(_Cls)>:: \
                               instance_known().allocate(); \
        if (ptr == NULL) \
            throw std::bad_alloc(); \
        return ptr; \
    } \
    static void operator delete(void* ptr) \
    { \
        if (ptr) \
            NVWA::static_mem_pool<sizeof(_Cls)>:: \
                           instance_known().deallocate(ptr); \
    }

Declares the normal (throwing) allocation and deallocation functions.

This macro uses the default group.

Parameters:

_Cls

class to use the static_mem_pool

_Cls

)

Value:

public: \
    static void* operator new(size_t size) _NOEXCEPT \
    { \
        assert(size == sizeof(_Cls)); \
        return NVWA::static_mem_pool<sizeof(_Cls)>:: \
                              instance_known().allocate(); \
    } \
    static void operator delete(void* ptr) \
    { \
        if (ptr) \
            NVWA::static_mem_pool<sizeof(_Cls)>:: \
                           instance_known().deallocate(ptr); \
    }

Declares the nothrow allocation and deallocation functions.

This macro uses the default group.

Parameters:

_Cls

class to use the static_mem_pool

DECLARE_STATIC_MEM_POOL_GROUPED__NOTHROW

#define DECLARE_STATIC_MEM_POOL_GROUPED	(	_Cls,
		_Gid		)

Value:

public: \
    static void* operator new(size_t size) \
    { \
        assert(size == sizeof(_Cls)); \
        void* ptr; \
        ptr = NVWA::static_mem_pool<sizeof(_Cls), (_Gid)>:: \
                               instance_known().allocate(); \
        if (ptr == NULL) \
            throw std::bad_alloc(); \
        return ptr; \
    } \
    static void operator delete(void* ptr) \
    { \
        if (ptr) \
            NVWA::static_mem_pool<sizeof(_Cls), (_Gid)>:: \
                           instance_known().deallocate(ptr); \
    }

Declares the normal (throwing) allocation and deallocation functions.

Users need to specify a group ID.

Parameters:

	_Cls	class to use the static_mem_pool
	_Gid	group ID (negative to protect multi-threaded access)
