UB_LOG

#define UB_LOG	(		level,
			...
	)		UB_LOG_##level(__VA_ARGS__)

UB_LOG(level, formt, ...), level is compared to the level in the category which is defined by UB_LOGCAT.

UB_LOGCAT must be defined in .c file to indicate the log category index. UB_LOGCAT=0 is reserved as this unibase category. e.g. UB_LOG(UBL_DEBUG, "%s:x=%d\n", func, x); if UBL_DEBUG<="the level in UB_LOGCAT", it is printed

UB_TLOG add timestamp regardless the timestamp option in the category.

UB_VLOG

    else if((var)==UBL_ERROR){UB_LOG(UBL_ERROR,__VA_ARGS__);}\
    else if((var)==UBL_FATAL){UB_LOG(UBL_FATAL,__VA_ARGS__);}\
    else{;}

UB_VLOG allows for flexible logging with a variable log level specified as an argument in the function call. Example Usage: void func(int level, int abc) { UB_VLOG(level, "hello world\n"); } The func can be called as: func(UBL_DEBUGV, abc); In this case UB_LOG and UB_TLOG can not work.

			s,
			m
	)

Value:

    static inline int name##_toggle_bit_field(uint32_t x)       \

			ts2
	)

Value:

        {               \
        int64_t ns_ub_m_=(int64_t)UB_TS_ADD64NS(ts1,ts2);   \
        UB_NSEC2TS(ns_ub_m_,rts);           \
    }

rts=ts1+ts2 in 64-bit nanosecond unit

UB_HTONLL

#define UB_HTONLL

(

x

)

Value:

           ((1==htonl(1)) ? (x) : ((uint64_t)htonl((x) & 0xFFFFFFFF) << 32) | \
           htonl((x) >> 32))

convert values between host and network byte order. which converts the unsigned integer host long long from host byte order to network byte order.

UB_NTOHLL

#define UB_NTOHLL

(

x

)

Value:

           ((1==ntohl(1)) ? (x) : ((uint64_t)ntohl((x) & 0xFFFFFFFF) << 32) | \
           ntohl((x) >> 32))

convert values between host and network byte order. converts the unsigned integer netlong from network byte order to host byte order.

UB_STATIC_ASSERT

#define UB_STATIC_ASSERT	(		cond,
			error
	)		typedef char type[(cond) ? 1 : -1]

assert during compilation time. When cond is equal to true, no error. Otherwise, compilation error is raised. e.g. UB_STATIC_ASSERT(uint8_t == 1, Uint8InvalidSize)

UB_PROTECTED_FUNC

#define UB_PROTECTED_FUNC	(		cbfunc,
			rval,
			...
	)

Value:

    int ub_func_private_mutex_lock(void); \
    int ub_func_private_mutex_unlock(void); \
    ub_func_private_mutex_lock(); \
    rval=cbfunc(__VA_ARGS__); \
    ub_func_private_mutex_unlock();

call the cbfunc with an internal mutex protection. The ub_func_private_mutex_lock() and ub_func_private_mutex_unlock() are only used privately in this macro. Please do not use them freely elsewhere.

UB_PROTECTED_FUNC_VOID

#define UB_PROTECTED_FUNC_VOID	(		cbfunc,
			...
	)

Value:

    int ub_func_private_mutex_lock(void); \
    int ub_func_private_mutex_unlock(void); \
    ub_func_private_mutex_lock(); \
    cbfunc(__VA_ARGS__); \
    ub_func_private_mutex_unlock();

similar to the UB_PROTECTED_FUNC without return value rval
