Interprétation d'un #define

Bonjour.
J'ai le #define suivant que j'ai du mal à interprêter:
*****************Code************************

Code:

1
2
3
4
5
6
7
8
9
10
11
#define ARRCV2_SET_BAUDRATE(lt_T1,lt_T1LeftDelta,lt_T15LeftDelta,lt_T2LeftDelta,\
lt_T1RightDelta,lt_T15RightDelta,lt_T2RightDelta)\
{\
	rt_T1 = lt_T1;\
	rt_T1LeftDelta = lt_T1LeftDelta;\
	rt_T15LeftDelta = lt_T15LeftDelta;\
	rt_T2LeftDelta = lt_T2LeftDelta;\
	rt_T1RightDelta = lt_T1RightDelta;\
	rt_T15RightDelta = lt_T15RightDelta;\
	rt_T2RightDelta = lt_T2RightDelta;\
}

********************************************
et il est utilisée de la façon suivante :
*****************Code************************

Code:

1
2
3
ARRCV2_SET_BAUDRATE ((T_TimeStamp)ARRCV2_MC_PERIOD_CC,
	                    (T_TimeSpan)ARRCV2_T1_LEFT_DELTA_CC, (T_TimeSpan)ARRCV2_T15_LEFT_DELTA_CC, (T_TimeSpan)ARRCV2_T2_LEFT_DELTA_CC,
                    (T_TimeSpan)ARRCV2_T1_RIGHT_DELTA_CC, (T_TimeSpan)ARRCV2_T15_RIGHT_DELTA_CC, (T_TimeSpan)ARRCV2_T2_RIGHT_DELTA_CC);

********************************************

Remplace la ligne

Code:

1
2
3
4
5
ARRCV2_SET_BAUDRATE ((T_TimeStamp)ARRCV2_MC_PERIOD_CC,
                                            (T_TimeSpan)ARRCV2_T1_LEFT_DELTA_CC, 
                                            (T_TimeSpan)ARRCV2_T15_LEFT_DELTA_CC,
                                            (T_TimeSpan)ARRCV2_T2_LEFT_DELTA_CC,
 ....etc

par

Code:

1
2
3
4
5
6
7
{
	rt_T1 = (T_TimeStamp)ARRCV2_MC_PERIOD_CC;
	rt_T1LeftDelta = (T_TimeSpan)ARRCV2_T1_LEFT_DELTA_CC;
	rt_T15LeftDelta =(T_TimeSpan)ARRCV2_T15_LEFT_DELTA_CC;
.... etc
 
}

Re : Pb de #define

Merci bcp
