[edk2] [PATCH] VfrCompile: fix invalid comparison between pointer and integer
Posted by Paolo Bonzini 8 years, 12 months ago 
This would be valid C but is not valid C++, so change the comparison
to do what it has always been doing.

Is it intended that "-s ''" is not an error, rather it is the same as no
option at all?

Hi Paolo,

"-s ''" is an error, current the error message is not same as no option, because the content after the " all be treated as -s 's input.
May I know what's your comment on  Nikolai SAOUKH's patch ?

-  if (mStringFileName == '\0' ) {
+  if (mStringFileName == NULL || *mStringFileName == '\0' ) {


Best Regards,
Zhu Yonghong

If "-s ''" is an error, it should be pointless to check *mStringFileName.

Hi Paolo,

Yes, I agree with you.  I also add Nikolai SAOUKH in loop in case he may have different comment.
