Re: [ros-dev] [ros-diffs] [cgutman] 41783: - Fix return value of tdiGetMibForIfEntity so it doesn't return a failure status on success

[Ged]

This looks hackish
It also breaks the log as you're potentially returning something different from what
the log states

[Cameron Gutman]

It's not a hack. We know we have succeded if we reach that  code  
because we check for failure earlier. The problem is that status was  
the return value of DeviceIoControl which returns nonzero for success  
but zero is success in ntstatus.

The hack is storing a BOOL value in an NTSTATUS variable.

Yeah, I should have stated this more clearly.

 

My point was DeviceIoControl returns TRUE, you then print this to the log as
an NTSTATUS value which now holds the value '1' which in NTSTATUS terms is
STATUS_WAIT_0 + 1

After this you then return STATUS_SUCCESS which is 0.

 

As I said, it's rather hackish.  J
