I am calling GetDiskFreeSpaceEx from my application, we have filter driver, when low resource from driver verifier is running, In filter driver memory allocation fails then we return the status to IoManager, but from the application GetDiskFreeSpaceEx is not returning, it hungs.
low resource from driver verifier is configured only for our filter driver.
When I see the myComputer explorer , not seeing any partition, not able to click anything on toolbar.
I just want to know why GetDiskFreeSpaceEx API hungs, any help is appreciated.
Thanks in Advance.
Regards
Sharan
Are you also completing the I/O request when you return a failure status?
