请教一段程序，没看懂，对枚举值比较不理解

只看该作者 · 2010-7-7 13:08

typedef enum
{
drTanklessStatePowerOnInit = 0,
drTanklessStateWorking = 1,
drTanklessStateStop = 2,
} TTanklessState;
TTanklessState sTanklessState;

typedef enum
{
drIgnition = 0,
drTansferFire = 1,
drTempControl = 2
} TTanklessWorkingSubState;
extern TTanklessWorkingSubState sWorkingSubState;

TByte rGasPressRlease;
TByte rGasPressRlease;

if (((sTanklessState == drTanklessStateWorking) && (sWorkingSubState > drIgnition)) && (rGasPressRlease))
{

}

上面if后面是如何判断的啊，请高手指教下，谢谢！
