Member Function Documentation

UMisItem::ResultValue UMisLoop::evalCondition	(	UVarCalc *	calc,
		bool *	val
	)

evaluate the loop condition

Parameters

calc	is the UVarCalc object with the local variables
val	is where the boolean result is returned

Returns

RV_OK if expression is evaluated, else RV_SYNTAX_ERROR
