Setting the Type

Plug-ins
#1

basic question again.

I wonder if it is necessary to set the type in this case. In the first code below I do not set the type for ZTCellHeight

	arg6[0].type = VAR_STRING;
	arg6[0].string = (char *)gSite.Alloc(100);
	strcpy_s(arg6[0].string, 100, "ZT Cell Height");
	arg6[1].type = VAR_FLOAT;	arg6[1].val = 20.0f;
	arg6[2].type = VAR_FLOAT;	arg6[2].val = 5.0f;
	arg6[3].type = VAR_FLOAT;	arg6[3].val = 200.0f;
	arg6[4].type = VAR_FLOAT;	arg6[4].val = 1.0f;
	arg6[5].type = VAR_FLOAT;	arg6[5].val = 0.0f;
	AmiVar ZTCellHeight = gSite.CallFunction("Param", 6, arg6);

here I do set the type for ZTCellHeight:

	arg6[0].type = VAR_STRING;
	arg6[0].string = (char *)gSite.Alloc(100);
	strcpy_s(arg6[0].string, 100, "ZT Cell Height");
	arg6[1].type = VAR_FLOAT;	arg6[1].val = 20.0f;
	arg6[2].type = VAR_FLOAT;	arg6[2].val = 5.0f;
	arg6[3].type = VAR_FLOAT;	arg6[3].val = 200.0f;
	arg6[4].type = VAR_FLOAT;	arg6[4].val = 1.0f;
	arg6[5].type = VAR_FLOAT;	arg6[5].val = 0.0f;
	AmiVar ZTCellHeight; ZTCellHeight.type = VAR_FLOAT;
	ZTCellHeight = gSite.CallFunction("Param", 6, arg6);

however, they both seem to work and I didn’t get problems so far. Could someone maybe comment what best to use?

thanks, Ed

No, you don’t need to do that because CallFunction returns entire variant structure (i.e. value AND type)
